Bug ID: 466622
Summary: kwin_x11 entire desktop freeze, mouse still works,
killing kwin_x11 fixes, seems to only be on kernels
newer than 6.1.8 for me (intel i915)
Classification: Plasma
Product: kwin
Version: 5.27.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: j.straight-...@straights.net
Target Milestone: ---
I'm not really sure if this is entirely upstream, because the only thing it
seems to affect is kwin. No other programs freeze or crash.
My desktop will randomly freeze and require me to switch to a vtty and kill
kwin_x11, which then gets restarted and everything is fine. The image is frozen
- the desktop is not. So I'm _guessing_ it's related to compositor and effects.
Even though the desktop image is frozen, the audio continues to play, and I can
click where the (now frozen) video controls are to pause and restart the audio.
I have filed this bug on the i915 drivers bug tracker here:
https://gitlab.freedesktop.org/drm/intel/-/issues/8226
It only started happening after changes to i915 post 6.1.8. Linux 6.1.8 has
been perfectly stable for me.
Originally, I thought it only happened during playing videos in a browser, but
it has since happened while not doing that, but it seems to happen more (often)
while playing videos. I might go a couple days, or I might have 2 freezes in 10
minutes.
Maybe someone can tell me what I might be able to do to enable some debugging
logging for kwin and the compositor effects to help us pinpoint what's causing
this?
Thanks.
Next time it happens, I'll try alt-shift-f12 before killing it. I tried that
earlier today, but I had the key combo wrong I think.
