Windows 10 missing application repaints

I'm seeing many applications missing their screen repaints, e.g., popup menus come up blank until I mouse over them, Explorer selection not painted when I click on an item, Event Viewer not repainting after a scroll unless I resize the frame, etc.

Basically same problem as described in 2017's https://answers.microsoft.com/en-us/windows/forum/all/windows-10-issue-screen-is-not-redrawn-properly/d0fcf284-0066-4fa0-b8f8-54f93e9a7d32, except that I am running a single monitor. I believe this started when I upgraded to an HP 34F Curved (3440 x 1440 - very large pixel count). CPU utilization is low; number of apps open can be as low as one.

    Do you experience the same if you opt a Clean Boot or after creating a new user account?

    @Lloyd Smith
    Hi,

    If disabling hardware acceleration is an option for you?

    According to you description, download Process Monitor and see what happen when missing application repaints maybe useful.
    https://learn.microsoft.com/en-us/sysinternals/downloads/procmon

    Hope above information can help you.

    I'm not able to reproduce the problem this evening. - this afternoon I had it for several hours across a couple of restarts. Last thing I tried this afternoon was a run of 'SFC /SCANNOW' and then a safe boot at network level with all non-MS services disabled. That env did not exhibit the problem (though resolution there was only ~ 1280 x 1024).

    So, when and if this recurs, I will check:

    • Does a lower resolution fix the problem
    • Is there a non-MS service causing the problem (disable one by one, I guess)
    • Does it occur in a new, clean account on this machine

    Because scrolling windows are not repainting, using Procmon might not be much fun. But as I said, the machine did not have much CPU usage when the repaints were failing (nor file or disk usage either).

    I do not see any setting for hardware acceleration for this graphics adapter.

    Thanks.

    I've gotten this twice again since original posting last week, both after restarts of Windows. Switching display resolutions down (e.g. 1920 x 1200) fixes it, and problem is not seen after immediately switching back up to 3440 x 1440. This workaround only costs a few minutes of lost time.
