Created attachment 141984 [details] STDOUT and qdbus support information. Zipped because I can't attach two files SUMMARY System settings flickers heavily, GUI elements (buttons, text etc.) completely disappear before returning after some time, and the left panel is commonly replaced by a full-white column. Stdout provides very little useful information, but I've attached it anyways. Baffling detail: When I recorded System Settings with OBS to provide a video file showcasing the bug, it didn't reproduce. I closed OBS and tried the app immediately again, and sure enough, the bug was still there. It seems like OBS recording solves this bug??? I'm currently using the 5.23 beta but this also happened on 5.22.5, though it looks like the 5.23 beta has made it worse. STEPS TO REPRODUCE 1. Open System Settings 2. Navigate to anywhere or click on any element 3. See graphical corruption OBSERVED RESULT System settings has unusable amounts of graphical corruption EXPECTED RESULT System settings working without graphical errors SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux / 5.22.90 KDE Plasma Version: 5.22.90 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2+kde+r227-1 Mesa Version: 21.3.0_devel.145344.112d526f778-1 GPU: Intel RocketLake-S GT1 [UHD Graphics 750] (rev 04) ADDITIONAL INFORMATION
Wayland or X11?
Wayland.

Heavy flickering, text and buttons pop in and out of existence constantly, and the left panel (where the different setting panels live) completely disappears, and gets replaced by just a full-white column. One detail that may be useful: The Startup->Background Services tab and Display Tab trigger this bug much faster. So maybe that can shed some light as to the cause.
Can you change "tearing prevention" option in compositor settings to "fullscreen repaints" and check whether visual artifacts are still present?

Sigh, right, it's not wired in on wayland. Can you please add "KWIN_USE_BUFFER_AGE=1" to /etc/environment and restart session?
correction: KWIN_USE_BUFFER_AGE=0
(In reply to Vlad Zahorodnii from comment #8) > correction: KWIN_USE_BUFFER_AGE=0 Done. Bug is still present. The left panel being replaced by a white column seems to happen less, but might be just a new-session, random fluke thing.

Update: Yep, it was a random fluke thing, the left panel issue also reproduces now.
It looks like you use dev branch of mesa, can you reproduce the issue with stable mesa?
(In reply to Vlad Zahorodnii from comment #11) > It looks like you use dev branch of mesa, can you reproduce the issue with > stable mesa? I can't test it, because stable mesa will segfault due to being built against LLVM 12, and I can't compile it myself because stable mesa uses LLVM member functions that have been removed in later versions. Are there any logs that I could provide that would help you tell if it's related to mesa or not?
Can't reproduce issue after a clean system reinstall. It was probably something to do with my other system packages.
