Bug ID: 372443
Summary: Kwin crash when pressing alt tab using cover switch
Product: kwin
Version: 5.8.3
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: alden.weddle...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.8.3)
Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.4.0-47-generic x86_64
Distribution: KDE neon User Edition 5.8
-- Information about the crash:
- What I was doing when the application crashed:
Opening Kmail via the application menu. I believe it crashed when I hit alt
tab. Was using the cover switch type. After the crash the switch method being
used is breeze. The setting menu still shows cover switch as the primary
method and breeze as the alternate method.
-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
