You can also see that the mouse pointer is seen twice in the lower left corner.
In the moment the artifacts seem to be gone. I will try to figure out in which situation they start appearing (again). For any hints I'd be thankful! Created attachment 136486 [details] Screenshot from a screenrecording from a person on reddit I've noticed that someone published a screen recording of a Plasma 5.21 session in which the same artifacts can be seen [1] at second 13-14. I made a screenshot and attached it here. This at least proofs that it's not only me who is affected. [1] https://www.reddit.com/r/kde/comments/m07uoy/any_kind_of_window_tiling_is_not_working_on_kde/ It would be interesting to see if the artifacts go away permanently when compositing is turned off. I mostly (or only?) see those graphical issues now at Firefox 89's file download dialog. I will try to capture a screenshot, but the distortion vanishes very quickly. Could be related to https://bugs.kde.org/show_bug.cgi?id=437893 somehow? At least symptoms look similar. Created attachment 139512 [details]

It has also been happening: - without compositing - on wayland (In reply to Dimitris Kardarakos from comment #8) > Kirigami Gallery colors page and Task Manager indicator artifacts. At least I don't have this issue and it may be a different one. I had similar artifacts after upgrading to 5.23. Finally I had a look at ~/.config/kwinrc and found: [Compositing] AnimationSpeed[$d] Backend=OpenGL Enabled=true GLColorCorrection=false GLCore=true GLPlatformInterface=egl GLTextureFilter=2 HiddenPreviews=5 OpenGLIsUnsafe=false UnredirectFullscreen=false XRenderSmoothScale=false after I removed GLPlatformInterface=egl GLTextureFilter=2 all work fine again. I also have Intel HD Graphics and running a X11 session. One last note: I only had artifacts in Qt programmes. I just saw in one of Niccolò's last videos, that he experiences the same issue [1], when he opens Discover: 1) only the title is displayed but the background fills the window's content and 2) while resizing it flickered two times with a very similar pattern as described in this bug report. [1] Challenge: Use KDE Plasma ONLY With Touchscreen! https://tube.kockatoo.org/w/76xwD2mHFm7CF8j11cZcMr?start=5m42s --- > after I removed > GLPlatformInterface=egl > GLTextureFilter=2 > all work fine again. I will test later if this triggers it also for me, thank you!
