Bug ID: 390892
Summary: kwin crash
Product: kwin
Version: 5.12.2
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: mic...@sutkowski.pl
Target Milestone: ---
Application: kwin_x11 (5.12.2)
Qt Version: 5.9.1
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-36-generic x86_64
Distribution: Ubuntu 17.10
-- Information about the crash:
I logged in to my KDE and noticed, that there is no frames around windows. I
cannot move, focus them or do anything. I'm using X11 session as Xwayland
doesn't work at all (it's unable to login, session immediately ends and
fallbacks to login manager).
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
