Bug ID: 403260
Summary: Crashed after changing kwin rules for konsole
Product: kwin
Version: 5.14.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: szc...@op.pl
Target Milestone: ---
Application: kwin_x11 (5.14.4)
Qt Version: 5.11.3
Frameworks Version: 5.53.0
Operating System: Linux 4.19.14-300.fc29.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
1) Made changes to kwin rules for Konsole (window behaviour, rules matching
desired windows)
2) Restarted Konsole
3) Windows decorations went for a lunch
- Unusual behavior I noticed:
None of the changes made with strict window matching (title, window class, etc)
changed application behaviour. Resetting changes to match whole application
(konsole) triggered the issue.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
28 return SYSCALL_CANCEL (nanosleep, requested_time, remaining);
