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?
