Description Marián Konček 2022-10-10 10:18:12 UTC 
Info:
happens on both Fedora 37 and 38
using X11
KDE Plasma version: 5.25.5
Qt version 5.15.6

From time to time, like once per several hours the whole screen goes black for about a second then it goes back to normal. It takes a total of about 2 seconds to return. It seems like everything works properly afterwards other than the fact that minimizing any window sets its minimized size to the whole screen instead of what was there previously.

I use 2 monitors on both setups where i noticed this. I also noticed this started happening after updating from Fedora 36 or Fedora 35, I am not sure.

It happens often while in Alt + Tab selection but I noticed it also happening when I was just looking at screen.
Comment 2 Marián Konček 2022-10-11 11:33:45 UTC 
Should i look for some specific logs when this happens?
