Zoomed images unexplained panning

Hi all,
I've run into a bizarre issue on my new iMac, running LR Classic 11.31. In Library or Develop module, when I zoom an image in loupe mode, it begins to very slowly pan from right to left, as long as my cursor is hovering over the image area. As soon as I move my cursor away (say, over a side panel) the panning stops. It's as if I was slowly dragging the cursor to pan the image, except the mouse is stationary.

Also, if I hover over the filmstrip in Library module, it starts panning slowly towards the first image in the filmstrip row (ie. from right to left).

This started happening without warning overnight, and I hadn't changed any settings.

To try to solve this I have:

  1.  Uninstalled and reinstalled LR Classic without resetting preferences
  2.  Uninstalled and reinstalled LR Classic, resetting preferences
  3.  Uninstalled v11.31 and installed the previous version 11.3
  4.  Rebooted my Mac several times
  5. Deleted the plist, rebooted and reset preferences
  6. In case it was actually a mouse issue I have changed mice

 

None of these steps have made any difference. It's as if LR thinks I'm scrolling across the image, or across the filmstrip, when I'm actually doing nothing.

I'm at my wit's end. Any thoughts?

 

In case it helps, here is my system info:

Aargh. Sorry, folks, this may not be a Lightrom issue at all, as I've just discovered more unexplaining panning when I insert my mouse cursor in a web form. I'll post here when/if I figure out what is going on!

This did indeed prove to be a non-Lightroom issue. I'm still not certain what happened, but the issue disappeared after I switched mice and keyboards, though that may have been a coincidence. I suspect something on the OS level. I wish I knew why the problems have disappeared, but I'm delighted that they have!
