Rob - the pre-release builds don't overwrite your normal install - and don't take over your file associations, so they're easy enough to have running in tandem so you can test specific changes (in case you were worried on either score).

@Sanyam any updates on this? I'm VERY wary of installing a pre-release build unless it 100% doesn't have any issues. I also hit this message when trying to use your link:

Hi, sorry - I realise now I've mean smushing together the terms 'Scrubby' and 'Animated' Zoom - thinking they were the same thing. Basically never use 'Animated Zoom' (click and hold) so I've always been on about 'Scrubby Zoom' (click and drag)!

So - Scrubby Zoom update. Another pre-release build seems to have changed the behaviour a bit again (appears to just be v20.5, slightly confusingly).

It's now much more consistent. The further over to the right of the screen, the more accurate it is - the further to the left of the screen it is, the more it'll be off by (it'll zoom in on a point that's not far enough left for the point at which the cursor initiates the zoom).

Screen recording attached.

Here's a screen recording... I thought the lower boundary one might mean it's taking account of the pasteboard when figuring out the region it's 'allowed' to zoom in/out within - where Photoshop doesn't care as it doesn't have an equivalent pasteboard.

But anyway - you can see, mid page, it's pretty much right now. Closer to the edges, not so much.

Got it now ('check for updates' doh!).

It's much, much better, thank you. You're in the right ballpark, consistently.

It's still not quite as accurate as Photoshop's Scrubby Zoom though, particularly towards the edges of the page and especially at the end of the document (bottom boundary)...

Doesn't seem to be showing up in the pre-release tab yet (just Illustrator). Will keep an eye out.

I put a shiny new 5070TI 16 GB into my PC, and GPU preview goes crazy. Animated zooming don't work at all and crashes my Indesign. I have cleaned drivers, installed latest one. Reinstalled Indesign! Indesign sees my card (but only 4 gigs) - my expirience is awfull... I have a lerge 5k monitor - if it helps... Latest indesign 20.4.1

Disregard my previous comments, this is still occurring.

Appreciate the update Sanyam, this is incredibly frustrating. I suspect there are many others dealing with it who just haven't been able to articulate the issue as well as Mhast did.

Update: maybe premature and I'm sure just a temporary fix, but I think changing the anchor point while zoom tool is selected has helped. Doesn't seem which anchor even matters, just changing it seems to have stopped the crazy jutter.

Having this exact same issue and it's driving me nuts. Been googling for hours but it's hard to search for. Part of me is wondering if it's related to using an external monitor with my macbook pro.

Screen capture of v20.4.1 behaviour.

v20.4.1 still seems to display the behaviour...

Some context - I am using a wacom tablet (for both the expected behaviour with scrubby zoom in Photoshop and the weird behaviour in InDesign).

Doing a very slow zoom, it seems to jump initially and then if you carry on zooming it'll try to aim for where you original had the cursor (though that's not that helpful if the zoom amount you wanted is somewhere in between).

I thought I had the same issue but in reality, believing I was doing well, I had unticked the multi gesture box in the interface preference pane (since I don't own an external trackpad). But it seems Logi options+ uses the multi gesture functionalities to communicate with MacOS apps.

Easiest to compare the expected behaviour with scrubby zoom on Photoshop (see screen recording). You stick your cursor over what you want to centre the zoom on, engage the zoom, scrub to the zoom level want and release - without having to then adjust the focus of attention with the hand tool because you've ended up somewhere unintended.

This screen recording demonstrates the behaviour: I'm trying to zoom in on each of the dishes but it sort of jumps all over the place en route and sometimes just ends up focussed on something other that what I was hovering over when I started the zoom. It's almost like it's taking into account the pasteboard bounds or something?
