https://bugs.kde.org/show_bug.cgi?id=365918 --- Comment #16 from Chris --- It came back again. (All I did was open a Konsole window.) While the glitching was happening, I went into Desktop Effects and tried disabling Blur and Contrast, but the glitching continued. Then I restarted kwin (using `killall kwin_x11' then `kwin_x11 --replace &') and the glitching was no longer happening, as expected. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=365918 --- Comment #15 from Chris --- Switching the compositor backend to XRender would fix the problem, though if I switched back to OpenGL during the same session, I think the problem was still there. Rebooting is not required, I could also log out back to SDDM, and log back in again. Didn't test restarting kwin without logging out, didn't know that was an option. I've definitely noticed it start happening when I wasn't in fullscreen. I wish I had written down exactly what I was doing when it started happening those few times it happened.

https://bugs.kde.org/show_bug.cgi?id=365918 --- Comment #14 from Thomas Lübking --- Is rebooting required or does switching the compositor backend or restarting kwin clear the stage as well? You could disable the two effects but that would only provide negative knowledge, of course (ie. if it still happens, it's not them) Could it be related to running fullscreen games (steam et al.)? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=365918 --- Comment #13 from Chris --- I actually still can't figure out how to trigger that behavior when I want to. It just seems to happen randomly. I've since rebooted, which gets rid of the issue indefinitely. It may crop up again, as it did before. Should I go ahead and disable those effects anyway (and change the buffer method too?) and see if it comes back? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=365918 --- Comment #12 from Thomas Lübking --- The flicker is due to the re-used buffer, the question is why one of them is invalid but for the newly exposed area and this seems to be related to window decorations. Let's start with the obvious: pelase deactivate blur and contrast effects (kcmshell5 kwineffects) and see whether it's still a problem. You can also try export KWIN_USE_BUFFER_AGE=0 kwin_x11 --replace & and see what happens (this will read the old data from the front buffer instead of relying on the buffer_age extension) -- You are receiving this mail because: You are watching all bug changes.

I did try that ("Switch to one of the two OpenGL backends") and it didn't work,
unfortunately.

https://bugs.kde.org/show_bug.cgi?id=365918 --- Comment #8 from Chris --- I should also mention: this doesn't happen if a window has no titlebar/frame as set in Window Rules. The flickering doesn't happen when I open Firefox, because I got rid of the titlebar/frame for it (I use Tree Style Tabs) and I just tested that with Dolphin, and the flickering doesn't happen when opening a Dolphin window now either. -- You are receiving this mail because: You are watching all bug changes.
