Summary: Kwin_x11 crash when toggling Compositing
Product: kwin
Version: 5.13.4
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: andre.vma...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.13.4)
Qt Version: 5.11.1
Frameworks Version: 5.49.0
Operating System: Linux 4.18.5-arch1-1-ARCH x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Toggling compositing with Alt+Shift+F12, on a relatively long session (couple
of days). Usually, it works on recent sessions, but can crash kwin on longer
lived ones.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
