Bug ID: 489677
Summary: KWin freeze seemingly randomly when Xwayland windows
are opened or many windows are opened
Classification: Plasma
Product: kwin
Version: git-stable-Plasma/6.1
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: input
Assignee: kwin-bugs-n...@kde.org
Reporter: gcaspe...@gmail.com
Target Milestone: ---
SUMMARY
Screen output buffer freezes for many seconds (30+), sometimes, even a few
minutes (max ~3), but all processes remain running in the background (Ex. I
still heard the video I'm watch in my headphones). Libinput still accepts input
events, but KWin fails to process them in a timely manor (over 40ms according
to libinput logs).
I'm assuming this is related to many Xwayland Chromium windows opened, but this
is just a hunch.
I have noticed something interesting with this. The longer I have the KWin
process running, the less I see these freezes.
However, on average, I get this behavior multiple times per day.
STEPS TO REPRODUCE
1. Run a Nvidia RTX 2000, 3000, or 4000 series gpu using the Nouveau driver
2. Open many Chromium windows (maybe ~5) and tabs (maybe ~10) with youtube.com
in them
3. Kill KWin, letting all the Chromium windows crash
4. Open Chromium again and "restore" the previous browser session
5. Screen freeze usually happens within ~30 minutes of use
OBSERVED RESULT
Random screen freezes described in summary
EXPECTED RESULT
No screen freezes
