Bug ID: 404198
Summary: KWin became unresponsive and presumably crashed after
opening VLC
Product: kwin
Version: 5.14.5
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: sephiroth...@hotmail.it
Target Milestone: ---
Application: kwin_x11 (5.14.5)
Qt Version: 5.12.0
Frameworks Version: 5.54.0
Operating System: Linux 4.20.6-xanmod4 x86_64
Distribution: KDE neon User Edition 5.13
-- Information about the crash:
- What I was doing when the application crashed:
I opened a video using VLC, then tried to quit VLC when the screen froze. I was
still able to move the mouse cursor around, but everything had become
unresponsive. I tried to open the same video again, but was not able to
reproduce the behaviour.
The crash does not seem to be reproducible.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
