What might cause the scroll zoom to reset constantly?

Sometimes when I'm playing back a clip and try to scroll-zoom-in for better detail the zoom will reset to full frame view over and over, not staying where I zoomed to. Other times it will stay where I put it.

The issue seems to be consistent though. If a bookmarked section has a problem staying zoomed in then it always has a problem. I can move to another section of the timeline and the same camera will stay zoomed in. Go back to the bookmarked section and it's constantly wanting to reset the view.

On the other hand, live view seems to behave properly staying zoomed for hours without problems.

One thing I have figured out is that if I zoom in, then change to another app in Windows, the zoom will stay fixed.

So far I haven't been able to find what is triggering a reset during playback. Any ideas?

I'm currently on v4.1, but this was happening on previous versions too and across multiple machines.

    Hi Jeff,

    I was unable to replicate the issue on my end.

    Could you provide the details of the layout you see this behavior on such as:

    Minimum Grid Size settings, Cell Aspect Ratio

    I found that if the zoom is slightly closer than the default aspect ratio, it will zoom back out. If zoomed in far enough, I was unable to make the zoom reset with or without bookmarks.

    If possible, you can also share a video of the zoom behavior for us.

    The layout isn't anything special and the zooming problem happens when clicked in to a single camera. 

    Here is a screen capture of the general layout.

     

    Here's a link to a video showing how it happens. About 35 seconds into the clip you'll see me click off to the desktop and the zoom stays put until I click back into DWS.

    I can go to random locations on the timeline and it seems to stay put, including with live view. I think mostly the bookmarked sections seem to trigger the issue.

    Hi Jeff Jones,

    I tried reproducing the issue, just as my colleague,Derek Mangasarian, but couldn't reproduce it unfortunately.
    Would it be possible to add me as a cloud user to that specific system?
