2. InDesign freezing when pressing backspace in a text box of more than 500 or 600 words

   This only seems to be a problem when using long text boxes more than a few hundred words. InDesign starts to slow down while I'm typing, but if I then select text or press backspace (mostly the latter) then InDesign freezes for 10 to 15 seconds.

   I've searched the problem, but the only solution I have found is to try closing the info panel, but this seems to be a CS3 fix and doesn't work.

3. CC Files in InDesign not showing up

   I shared files using CC Files for teams using my work account, and the sync with my account on my home computer in the user folder/creative cloud files, however they don't show up in the START workspace when I launch InDesign. How do I get these files to show up in the application?

4. The order of Arabic digits is reversed when changing their character direction

   1. Adobe InDesign CC 2017.1
   2. Create a textbox, type Arabic characters including some digits. Change character direction from 'Default' to 'Right to Left'.
   3. Arabic letters are RTL, but Arabic digits are written LTR; So when you change character direction to RTL, they should be in their right direction.
   4. Letters are RTL, but digits are reversed. The problem is that Arabic script is written RTL, but its digits' direction is LTR. Just like when you move caret and logically it moves in correct direction.

6. Hyperlinks

   I use a lot of hyperlinks in a document which link to the individual products on our website for online ordering and stock levels.

   The Hyperlink panel frequently corrupts - I lose the ‘traffic light’ link status indicator and location of the link (page No.) - meaning I have to remove InDesign and execute a clean install to get the feature back.

8. Stop resetting settings with each update

   Every single time there is an update I have to redo keyboard shortcuts, workspace, save settings etc. Same if I need to install it on a new computer. Why is it 2027 and we don't have those settings carry over? It is so frustrating to start your work day and have to start over setting up each program as well as being bombarded with all the new features. Do you really think people have time for that?

9. PDF Export

   Adobe InDesign - Enough Is Enough! Fix Your Software Before Adding More Features!

   I am so incredibly frustrated and angry with Adobe right now that I simply have to speak up!

   I have been working with Adobe InDesign professionally for many years. But what has been happening with this software over the past two years is becoming absolutely unacceptable.

   With every new version, things seem to get worse, especially when it comes to PDF export.

   InDesign keeps crashing, and the worst part is that there is not even an error message! The program simply closes. No warning, no explanation, no indication of what went wrong.

   And this does not happen just once. It happens over and over and over again!

   I have a newspaper printing deadline tomorrow morning!

   I am under enormous pressure to finish the pages and deliver the print-ready PDF files on time. Instead, I am sitting here fighting with software that I can no longer rely on.

   To be perfectly honest, I am absolutely sick and tired of this!

   Adobe, before you keep introducing new AI features, effects, and whatever else you are working on, perhaps you should first make sure that your existing software actually works properly!

   What is the point of adding new features when I cannot even export a PDF file without the program crashing?

   I do not need more AI effects. I do not need more unnecessary features.

   I NEED STABLE, RELIABLE, PROFESSIONAL SOFTWARE THAT ACTUALLY WORKS!

   I pay for professional software, and I expect professional quality in return.

   I have been an Adobe customer for many years. InDesign used to be software I could depend on. But over the past two years, I have increasingly felt that something is going seriously wrong.

   The problems started gradually, but today has been an absolute nightmare.

   Constant crashes. No error messages. No explanation. The application simply disappears!

   Do you have any idea what this means for professionals who work under strict deadlines every single day?

   Do you understand how much time, energy, productivity, and peace of mind these problems cost us?

   I am not a casual user. I work professionally with InDesign, and my job depends on having reliable software.

   In newspaper production, printing deadlines are not optional. They are absolute deadlines that must be met!

   And when your software repeatedly crashes during something as fundamental as exporting a PDF, it puts our entire production process at risk.

   MY MESSAGE TO ADOBE IS SIMPLE:

   Stop focusing so much on constantly adding new features and start taking care of the basics!

   STABILITY, RELIABILITY, AND A FUNCTIONING PDF EXPORT MUST BE YOUR TOP PRIORITIES!

   I am not asking for miracles. I am simply asking for professional software that can reliably perform its most basic functions.

   After all these years as a loyal Adobe customer, I am now deeply disappointed, extremely frustrated, and genuinely angry.

   ADOBE, PLEASE GET YOUR SOFTWARE UNDER CONTROL!

   ENOUGH IS ENOUGH. THIS CANNOT CONTINUE!

   Adobe InDesign - Enough Is Enough! Fix Your Software Before Adding More Features!

11. German dictionary hyphenation sucks

    InDesign 21.6 on macOS 27.0.1: There are discrepancies between the German dictionary entries and the actual hyphenation—InDesign uses only the hyphenation rules from the German DUDEN dictionary, meaning that the hyphenation points entered by the user in the dictionary are not applied.

    Adobe, please fix this issue as soon as possible.

    See more under "[15.0.2.323 + 15.0.3.406] Big problem with unrecognized user dictionaries" in the Bug-Discussion-Group – Prerelease Forum.

13. PDF security permissions password

    With the new macOS Golden Gate 27.0 (and via the most up to date ID 21.6) when exporting to PDF from InDesign, there appears to be a bug which prevents you keying in a Permissions Password. The cursor is present in the box, but you are unable to type.

    This is imperative in our industry, when generating printing proofs. Please fix :-)

15. InDesign 21.6 freezes for 5 seconds when placing images ONLY when offline on macOS

    A severe 4-to-5 second application hang/freeze occurs every time a user attempts to place an image file while the Mac is disconnected from the internet. If the Mac is online, the lag disappears completely. This is a regression bug introduced in recent 21.x builds.Steps to Reproduce:Open Adobe InDesign v21.6 on macOS.Disconnect the computer from the internet (turn off Wi-Fi and unplug ethernet).Create a new, blank document.Press Cmd + D to place any standard image file (e.g., JPEG, PNG) stored on the local hard drive.Click on the document layout to place the graphic asset.

    Expected Result:The image should place instantly onto the layout canvas without hesitation.

    Actual Result:InDesign freezes entirely, displaying a spinning wait cursor or locking up the mouse pointer for roughly 4 to 5 seconds before the image finally drops onto the page.Crucial Diagnostic Variables (Verified):Network Status: The bug only triggers when the Mac is offline. If the computer is connected to the internet, images place instantly without any lag.Regression: Rolling back three versions prior entirely fixes the problem. The issue does not exist in older builds, pointing directly to a telemetry, asset verification, or cloud-feature timeout loop introduced in recent 21.x code.

    Tested: Verified on local files (not cloud-synced folders or network servers).

    Third-party utilities have been ruled out.

16. Open PDF in InDesign not properly working when a vector image is present (.ai or .eps)

    When we export a PDF from InDesign with the box "Preserve InDesign Editing Capabilities" checked, if we open the resulting PDF in InDesign, it is perfect, styles are preserved, guidelines, tables, Layers, Parent Pages... All is ok. (just as if a idml was included in the PDF)

    However, as soon as we include a .ai or .eps anywhere in the InDesign file, the exported PDF can no longer be imported back in InDesign with all format. Styles are lost or are named "Paragraph1", "Paragraph2", no more guidelines, no more Parent Pages, tables are not like before...

    We're trying again every time a new version of InDesign is out. This morning, it was InDesign 21.6 (Windows). Still the same problem.

17. InDesign 2026: CMYK objects on the pasteboard display darker with Overprint Preview or Separations Preview Body I am experiencing a displa

    I am experiencing a display issue in InDesign 2026 when using Overprint Preview or Separations Preview.

    CMYK objects placed on the pasteboard (outside the page) become significantly darker, while the same objects displayed inside the page remain correct.

    The same document does not show this issue in InDesign 2025.

    I have tested this issue in multiple versions of InDesign 2026:

    Version 21.4.1.4
    Version 21.5.1

    The same issue occurs in both versions.

    Environment
    Adobe InDesign 2026
    Versions tested: 21.4.1.4 and 21.5.1
    Mac mini M4 Pro
    macOS Tahoe 26.6.2 (25G83)
    Monitor: EIZO ColorEdge CX240
    Connection: USB-C to DisplayPort
    Issue

    I have CMYK text and graphic objects positioned so that they extend from the page area onto the pasteboard.

    In Normal Preview, everything displays correctly both inside the page and on the pasteboard.

    However, when print simulation preview modes are enabled, the objects on the pasteboard display incorrectly.

    When Overprint Preview is enabled

    When I enable:

    View > Overprint Preview

    the display changes as follows:

    CMYK objects inside the page → display correctly
    The same CMYK objects on the pasteboard → become significantly darker
    Placed photos on the pasteboard → may disappear

    The CMYK values of the objects are the same.

    The appearance changes specifically when the object crosses from the page area onto the pasteboard.

    Separations Preview test

    I also tested:

    Window > Output > Separations Preview

    Preview: Off
    Inside page → Correct
    Pasteboard → Correct
    Preview: Separations
    Inside page → Correct
    Pasteboard → CMYK objects become significantly darker
    The same issue occurs as with Overprint Preview

    Therefore, the problem also occurs when Separations Preview is set to Separations.

    Both Overprint Preview and Separations Preview produce the same incorrect display behavior on the pasteboard.

    Summary of test results
    Preview mode Inside page Pasteboard
    Normal Preview Correct Correct
    Separations Preview: Off Correct Correct
    Overprint Preview Correct CMYK becomes darker / images may display incorrectly
    Separations Preview: Separations Correct CMYK becomes darker / same issue
    Comparison with InDesign 2025

    I tested the same document in InDesign 2025.

    With Overprint Preview enabled, objects display correctly both inside the page and on the pasteboard.

    However, the issue occurs in InDesign 2026.

    I tested:

    Version 21.4.1.4
    Version 21.5.1

    and the same issue occurs in both versions.

    This appears to be a possible display regression or rendering issue introduced in InDesign 2026.

    Steps to reproduce
    Create a new document
    Create a text or graphic object with a CMYK fill
    Position the object so that it extends from the page onto the pasteboard

    Enable either:

    View > Overprint Preview

    or

    Window > Output > Separations Preview > Preview: Separations
    Compare the appearance of the object inside the page and on the pasteboard

    The CMYK object displays correctly inside the page but significantly darker on the pasteboard.

    Expected result

    The same CMYK object should display consistently and correctly both inside the page and on the pasteboard when Overprint Preview or Separations Preview is enabled.

    At minimum, I would expect the same behavior as InDesign 2025.

    I would appreciate it if others could test whether this issue can be reproduced on other systems, or confirm whether there has been an intentional change to pasteboard rendering in InDesign 2026.

    Screenshots are attached.

18. In Design bleibt immer hängen

    Ich kann keine Dokumente mehr bearbeiten. Der Curser der Maus dreht immer blau im Kreis. Ich kann keine Texte mehr abändern. Habe InDesign Version 21.5.1. Es geht so seit 2 Wochen, habe ganze Installation deinstalliert und jetzt wieder installiert. Es nützt nichts.

19. Image placing issue

    Hi,

    Whenever I place two or three images, the software becomes unresponsive and gets stuck. I have to force-close the application and restart it to continue working.

20. InDesign 2026 (macOS): every open CEP panel costs ~20–25% CPU continuously

    InDesign 2026 (macOS): every open CEP panel costs ~20–25% CPU continuously — the host redraws the panel at display refresh rate even when the panel is completely static

    Summary

    With any CEP (HTML) extension panel open, the InDesign process burns roughly
    20–25% CPU permanently on a 120 Hz display, with no user interaction and no
    activity in the panel. Each additional open panel adds the same again (three
    panels ≈ 75%). Closing the panel, or collapsing it to a dock icon, returns
    InDesign to its ~5% idle baseline immediately.

    Call-stack sampling shows InDesign's main thread spending ~67% of its time in
    -[MTKView draw] → PlugPlugOwl.framework, which on EVERY display-link tick
    allocates a new MTLTexture, runs a CPU pixel-conversion pass over the whole
    panel bitmap, and uploads the full bitmap with
    -[MTLTexture replaceRegion:mipmapLevel:withBytes:bytesPerRow:] — even though
    the panel's renderer (CEPHtmlEngine) is idle and has produced no new frame.
    The MTKView appears to be in continuous-draw mode at the display's native
    refresh rate rather than paused-and-drawn-on-demand.

    Illustrator 2026 on the same machine, with the same PlugPlugOwl 12.1.0.5
    build, does NOT show this: opening a CEP panel there adds no CPU at all. So
    the issue is in InDesign's hosting of the CEP view, not in CEP/CEF itself.

    Environment

    • Adobe InDesign 2026, version 21.5.1.73 (build 21510)
    • macOS 26.6.2 (25G83), Apple M1 (8-core), 16 GB
    • Display: DELL U2725QE, 3840×2160 at 120 Hz, UI scaled to 1920×1080 (2×)
    • CEP 12.1.0 (CSXS 12); PlugPlugOwl.framework 12.1.0.5 inside the InDesign app bundle; CEPHtmlEngine Chrome/99.0.4844.84
    • CEP PlayerDebugMode = 1 (unsigned development panels), but the panels used are ordinary HTML panels with no special CEF command-line flags
    • For comparison: Adobe Illustrator 2026 (30.8.0) — same machine, same PlugPlugOwl build — is unaffected
    • Persists after a full restart of InDesign: [ ] yes / [ ] no ← fill in

    Steps to reproduce

    1. Launch InDesign, let it settle, watch the InDesign process in Activity Monitor: ~5% CPU at idle.
    2. Open any CEP HTML panel. (Reproduced with three different in-house panels; the one used for the measurements below is a fully static page — no timers, no requestAnimationFrame, no CSS animations, no polling.)
    3. Do nothing. InDesign's CPU rises by ~20–25% and stays there for as long as the panel is open.
    4. Open a second and third panel: each adds ~20–25% more (≈75% with three).
    5. Close a panel: CPU drops by the same amount immediately. Collapse a panel to a dock icon: same — cost goes to zero.

    Expected

    An idle panel should cost ~0%. The host should redraw the panel's view only
    when CEF delivers a new frame.

    Actual

    The host redraws — and re-uploads the full panel bitmap to a NEW Metal
    texture — on every vblank, regardless of whether the panel content changed.

    Evidence

    1. It is the InDesign process, not the panel's renderer. With one static
    panel open (Activity Monitor): InDesign 50–58% (with sample running
    concurrently; ~30% without), the panel's CEPHtmlEngine process 0.8%. A Chrome
    DevTools Protocol CPU profile of the panel page over the same period was
    99.7% idle, and document.getAnimations() returned an empty list — the page
    produced no new frames.

    2. Call-stack sample (attached: indesign-sample-one-panel-open.txt,
    sample <pid> 5 at 1 ms). Of 3465 main-thread samples, 2310 (67%) are:

    -[NSApplication run] … __CFRunLoopRun → _dispatch_main_queue_drain
      → __23-[MTKView __initCommon]_block_invoke (MetalKit)
        → -[MTKView draw]
          → PlugPlugOwl +0xf0ea8 → +0xf03ec → +0xf07ec           (2302 samples)
              ├─ PlugPlugOwl +0xf0da4 → +0xf5b20/+0xf5b64/…   (1216 samples — a per-pixel CPU loop over the panel bitmap)
              ├─ PlugPlugOwl +0xf0874 → -[IOGPUMetalTexture replaceRegion:mipmapLevel:withBytes:bytesPerRow:]
              │     → AGX::Texture::writeRegion / processCompressedRegion2D   (342 samples — full-bitmap upload)
              ├─ PlugPlugOwl +0xf0744 → -[AGXTexture initWithDevice:desc:…] → IOGPUResourceCreate   (35 samples — a NEW texture every frame)
              └─ PlugPlugOwl +0xf087c → _xzm_free_large_huge   (freeing a large buffer every frame)
    

    The CEP CVDisplayLink thread in the same sample shows MetalKit's
    DisplayLinkCallback → dispatch_source_merge_data → _dispatch_runloop_queue_poke
    on every vblank — i.e. the MTKView is running with isPaused = NO /
    enableSetNeedsDisplay = NO at the display's refresh rate.

    For comparison, indesign-sample-panels-closed.txt is the same sample with
    all panels closed: the main thread is ~96% blocked in mach_msg and there
    are no PlugPlugOwl frames at all.

    3. The cost tracks the display refresh rate. Switching the display from
    120 Hz to 60 Hz (nothing else changed) roughly halved InDesign's CPU with the
    panel open (one measurement: 58% → 24%).

    4. The cost tracks the panel's pixel area. Resizing the panel larger /
    smaller moves InDesign's CPU up / down accordingly.

    5. A collapsed (icon-docked) panel costs nothing — consistent with the
    per-frame work being proportional to the view's size.

    6. Illustrator is unaffected. Same machine, same session, Illustrator
    2026 with a CEP panel open stays at ~2% CPU.

    Impact

    Every CEP extension — third-party and Adobe's own — costs a sustained ~20–25%
    of a CPU core per open panel on any 120 Hz display, which includes every
    MacBook Pro since 2021 (ProMotion). Users who keep two or three panels open
    have InDesign sitting at 50–75% CPU all day: lag, fans, battery drain, and the
    effect compounds with other work. Users are unlikely to attribute it to the
    panels since the panels themselves look idle and their renderer processes
    show ~0%.

    Related reports

    • InDesign 2022 17.3 – HIGH CPU when idle
      (community forum, Jul 2022 – Jan 2024, unresolved). Very likely this same
      bug seen from the outside: 30–40% idle CPU in the InDesign process itself
      (the reporter ruled out CEPHtmlEngine when staff pointed at it) on a 16"
      M1 Max MacBook Pro — a 120 Hz ProMotion display — persisting from 17.0
      through the 2024 release. The default workspace includes the CC Libraries
      panel, which is a CEP panel, so a user needs no third-party extension to
      hit it. Quick check for that thread's reporters: collapse the Libraries
      panel to an icon and watch the CPU drop.

    • High GPU load on macOS 26 Tahoe
      (Illustrator UserVoice, also reported for InDesign; status "Started",
      3 Aug 2026: "platform-level compositing issue … flagged with Apple",
      workaround in Illustrator beta 30.8.0.72). Adjacent but NOT the same
      issue — that one is WindowServer GPU with the app's CPU low, whereas this
      is CPU inside the InDesign process in its own MTKView draw. Please don't
      merge them; note that Illustrator 30.8.0, which carries that workaround,
      is the app that does NOT show this problem.

    Suggested fix

    In the InDesign side of the CEP view hosting (PlugPlugOwl's MTKView usage):

    • Run the MTKView paused (isPaused = YES, enableSetNeedsDisplay = YES) and call setNeedsDisplay only when CEF delivers a new frame (OnPaint), the way Illustrator's hosting evidently already behaves.
    • Reuse one MTLTexture per view rather than allocating and freeing one per frame, and skip the CPU conversion + upload when the frame is unchanged.

    Workarounds for affected users

    • Set the display refresh rate to 60 Hz (halves the cost).
    • Collapse panels to dock icons when not in use (cost goes to zero).
    • Keep panels closed rather than open-but-idle.
