Bug ID: 404271
Summary: KWin crashes when tab switching from mpv when
fullscreen
Product: kwin
Version: 5.14.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: jagannatha...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.14.5)
Qt Version: 5.12.1
Frameworks Version: 5.55.0
Operating System: Linux 4.20.0-pf4 x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Watching a video on mpv on fullscreen and tab swtiched repeatedly when the
system didn't respond.
- Unusual behavior I noticed:
The system didn't for sometime and then it did. At that point I noticed KWin
had crashed.
- Custom settings of the application:
mpv has some KWin rules for windows borders but nothing more than that.
-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
