Bug ID: 458549
Summary: Random whole screen flashes/flicker on the desktop on
Wayland
Product: kwin
Version: 5.25.4
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: nf.pere...@live.com
Target Milestone: ---
SUMMARY
***
On Wayland, the whole screen flashes or flickers randomly every few seconds.
Seems more frequent if an application, for example Firefox, is open, but
happens even with just the desktop and nothing else.
The screen flashes for what seems a single frame and then stays normal until
the next flash. I can't find a pattern.
If necessary I can record a video of the issue at slow-motion.
Using KWIN_DRM_NO_AMS=1 on /etc/environment fixes the issue.
***
STEPS TO REPRODUCE
1. Login into Plasma Wayland.
2. Wait a few seconds or minutes while moving the cursor or windows around.
3. Observe screen flashing at random.
