The attached Xorg logs are from March 8th so not recent enough... While the problem is happening please run this command to collect a newer log:

  journalctl -b0 > journal.txt

and attach the resulting text file here.

[hetman (hetman)]

done.

this is very strange, but when I did the log, I noticed that the artifacts stopped appearing. And I was very surprised because. I did not reboot the laptop - it was woken up (23:48:37 suspend entry (deep)).
I recorded the video at about 21:27 and this period is in the log.
Perhaps the reinstallation of some libraries between 21:27 and 23:48, primarily Qt, had an effect (teamviewer did not want to start for me).

The bug has been fixed but I have no idea how.

[hetman (hetman)]

the error has not been fixed, it's just that the artifacts do not start to appear immediately, but when the computer works a little

[hetman (hetman)]

I thought that this is possible due to warming up, but the temperature is normal

There is a strong suspicion that the problem is in the Plasma code. I logged out and entered the working gnome - until I found artifacts. Switched to Plasma - artifacts appear
