Mission control shows tiny windows for 1 (out of 8) desktops.

When I open mission control for one of my desktops the displayed windows are tiny (measured one at 8x12 pixels). The other desktops are fine. This also appears to be progressive. Yesterday the windows were larger than today but still smaller than they should have been.

Based on this (https://discussions.apple.com /thread/8515674) discussion I would guess that I could fix this by rebooting, but I'm hoping that there's a less disruptive way to fix this. (Like resetting mission control, or fixing whatever scaling factor mission control is using for this desktop. Note: I don't really want a solution like 'delete this desktop' since I have some applications tied to this desktop).

Here's a picture of just a part of the screen (Yes the image is El Capitan, but I am running Catalina).

After normal reboot, as expected, problem is resolved so safe boot not needed. But what to do if it shows up again? (My initial question). It has happened at least twice so far.

Thanks,

Hi Murdstone,

We understand that you're seeing white squares on your computer when using Mission Control. Does the issue persist in safe mode: Start up your Mac in safe mode - Apple Support

Take care.

As I stated in the initial question I think a reboot will solve the issue. I will verify that the next time I reboot (I try not to reboot unless needed because all my chrome and safari windows re arrange themselves, and I lose my terminal history sometimes).

Is there some benefit to booting in safe mode if a normal reboot fixes the issue? (Note: The problem does not show up immediately, so if start in safe mode and don't see the problem I feel like I'll be at the same place as I would be if I start normally and don't see the problem).
