Bug ID: 395295
Summary: Kwin crashes while closing application
Product: kwin
Version: 5.13.0
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: ignus.gracia+bugs.kde....@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.13.0)
Qt Version: 5.11.0
Frameworks Version: 5.47.0
Operating System: Linux 4.17.0-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- Custom settings of the application: I have a Kwin Script rule called
MACsimize installed (basically what it does is it puts a maximized app on a new
virtual desktop and once it is unmaximized removes the new virtual desktop and
puts the app it back where it came from - kinda like osx does - I feel like the
script messed something up and Kwin got confused).
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
