Bug ID: 399512
Summary: KWin crashed after TTY switch with
Application-Specific Settings
Product: kwin
Version: 5.13.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: rj.wha...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.13.5)
Qt Version: 5.11.2
Frameworks Version: 5.50.0
Operating System: Linux 4.18.12-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
Switched from KDE (X on tty1) to a TTY not running a display server (Konsole
was focused at the time of the switch) (ctrl+alt+4), then switching back to
KDE. The crash may have been from the switch to tty4 or the switch back to
X/KDE on tty1
- Custom settings of the application:
- Window class: konsole
- Position: Apply Initially: 3840,0 (beginning of second monitor)
- Maximized Vertically: Remember: Yes
- No Titlebar and frame: Apply Initially: Yes
The above settings remained in the settings editor after the KWin crash but
were not no longer enforced.
Another application (Slack - flatpak) also had 'No Titlebar and Frame: Apply
Initially: Yes' and was also not enforced after the crash, however the settings
were no longer enabled in the editor.
Perhaps an important note: my two displays do not turn on at the same time when
switching back from another tty or when they are turned back on after
inactivity; consequently all windows are then consolidated to the primary
display. This time, Konsole was still on the second display when I switched
back from tty4
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
