Bug ID: 389250
Summary: KWin crashes when using the task switcher
Product: kwin
Version: 5.11.5
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: unduthe...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.11.5)
Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.15.0-1-MANJARO x86_64
Distribution: "Manjaro Linux"
-- Information about the crash:
- What I was doing when the application crashed:
I was switching windows with alt + tab.
It happened every time I activated the task switcher while using the "breeze"
theme.
Once I changed the switcher's theme Kwin stopped crashing, even when using
"Breeze" back again.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
