I recently ran a package upgrade and went from Plasma 6.3 to 6.4. Ever since, I have been experiencing an increasing amount of graphical glitches with my system. Seemingly, screen updates are delivered out of order (exhibited by stuttery scrolling); or parts of windows disappear briefly.
The issue is periodic in nature, happens around every minute, occasionally. It’s rather difficult to capture and most often I encounter it in Vivaldi. It also happens when web pages scroll themselves with JS, occasionally, so it’s not necessarily tied to user input. I haven’t noticed it on videos (e.g. YouTube), but it does happen in the background, as it’s visible on the player UI or the captions, but not the video itself, typically.
There was a mildly similar, probably unrelated issue when I just started using EndeavourOS months ago - everything was fairly laggy and stuttery on Wayland, which forced me to use X11 for about a week or two, but I was persuaded to try Wayland again and the issue was gone, so I switched to it fully now. I haven’t yet tried going back to it as it’s a bit annoying, and I’d like to keep using Wayland.
