Bug ID: 374290
Summary: kwin often hangs
Product: kwin
Version: 5.8.3
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: platform-x11-standalone
Assignee: kwin-bugs-n...@kde.org

kwin backtrace while hanging
It happens here (openSuse 42.2, intel GPU) often (at least once a day) that
kwin just hangs and I can not interact with anything anymore on the desktop.
I just see the mouse moving but no click is acting anything, even Ctrl-Alt-Esc
X11 Server kill mode can not be activated.
I then switch to a VT console and kill -9 the kwin_x11 process. A normal kill
does not help.
In the last recent case this happened, I created a backtrace while in the VT,
which is attached here.
