[ID-4272075] Interactive PDF Buttons: Button bounding area expands after file conversion from older version to 21.0
InDesign 2026 v21.0.1
I've just verified and reproduced this interactive PDF button display bug by first confirming that several archived versions of the interactive PDF (created from archived InDesign Source files), all function perfectly and as expected. It is ONLY by opening one of those older, archived InDesign source file in the current 2026 v21.0.1 and exporting a new copy of that same Interactive PDF that the buttons all appear differently when clicked.
The expected result is to have interactive buttons that look clean and functional when clicked.
The actual result (only when exporting the Interactive PDF from the current version of InDesign, never before from previous versions), is that all the interactive buttons now show a black bounding box that surrounds and extends up above and beyond the boundaries of the buttons themselves. It's visual display bug specifically on buttons. This remains true even when the buttons DO NOT have any hover or click states assigned. It's a button element issue, not a visual state issue. (Although the Hover state has always been glitchy or "sticky" which is annoying, but not as bad as the black bounding box described here.
Screenshot examples from the exported interactive PDF have been provided.
Workaround:
1. Export the test document to IDML and use the IDML to export to Interactive PDF
2. Recreating the button entirely in InDesign 21.0 restores the correct clickable area. However, this is not ideal for users working with older templates containing many pre-existing buttons.
