I am experiencing recurrent visual artifacts across my desktop (horizontal static/blocky corruption and transient flickering). The issue is especially prominent in Brave/Chromium apps, but affects the desktop environment as well.
Things I already checked out
-
Kernel Logs (
dmesg): No GPU ring timeouts orGCVM_L2_PROTECTION_FAULTerrors reported. -
Compositor Logs (
journalctl -f _COMM=gnome-shell): Repeated warnings:Client provided invalid window geometry for xdg_surface#58 (brave-origin ...). Working around. -
Screen capture behavior: Screenshots/recordings do not capture the artifacts, pointing to a display presentation/panel timing issue rather than a render buffer corruption.
What I Have Tried So Far
-
Reset GPU tuning/undervolt profiles back to stock defaults in LACT.
-
Force-enabled native Wayland and Vulkan backends in Chromium/Brave (
--ozone-platform=wayland). -
Reinstalled
kernel,mesa-dri-drivers,mutter, andgnome-shellviadnf reinstall. -
The issue persists across fresh desktop sessions.
