Description alerikaisattera 2022-11-05 16:11:26 UTC

SUMMARY
Contents of certain windows randomly stop updating and either start flickering or freeze completely. Minimizing and restoring the window forces it to update but does not resolve the bug. Restarting KWin resolves the bug. When there are multiple windows of the same program open, only one is affected at a time.


STEPS TO REPRODUCE
Not reproducible. Has been observed so far with Brave, Minetest, Minecraft and Konsole.
1. Open one of the programs above and use it for a while. Few hours to days are needed
2. At some moment, for no reason, the window content will freeze

OBSERVED RESULT
No freezing should happen

EXPECTED RESULT
The window freezes and KWin must be restarted

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:

Reminds me of Bug 456511. Are you using X11? What Plasma version are you using?

I'm using X11. Currently using 5.26.2 but updated very recently, not observed this bug yet. This bug was present in 5.26.1

Thanks. Does the issue go away if you disable compositing with Alt+Shift+F12?
