Bug ID: 468880
Summary: Random kwin freezes
Classification: Plasma
Product: kwin
Version: 5.27.4
Platform: Neon
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: core
Assignee: kwin-bugs-n...@kde.org

SUMMARY
***
After upgrading to 5.27 I experience random kwin_x11 freezes multiple times a
day. It hapens on my two different laptops with different cpu and gpu, so it's
not hardware related.
Content of last active window may remain interactive but I can not switch to
other windows.
I have to switch into tty terminal with ctrl+alt+f2, kill kwin with pkill -9 -f
kwin (without -9 it doesn terminate) and then return back to desktop session
(kwin restarts automatically).
I have no exact way to reproduce, it just happens randomly. But on both
machines apps I often use are Firefox, Kate, Krusader, Thunderbird, Konsole,
Discord.
I've recorded a strace log if it's helpful https://pastebin.com/LqRmaaSd When
wreezed, strace stops printing anything. These are last 30 lines after freeze.
