Bug ID: 362137
Summary: Kwin Crash at screen shutdown
Product: kwin
Version: 5.6.3
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: d.d.huis...@gmail.com
Application: kwin_x11 (5.6.3)
Qt Version: 5.6.0
Frameworks Version: 5.21.0
Operating System: Linux 4.1.20-11-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"
-- Information about the crash:
As soon as I or the system turns of a screen Kwin seams to crash. This always
happens when all active screens are turned off.
The settings in X doesn't seam to change any thing. This crash happens when X
is setup in a way that screens can be plug-and-play. But even when you force X
to have a window size it also crashes.
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
