Bug ID: 395662
Summary: KWin crash on Activity change when using Latte
activities
Product: kwin
Version: 5.12.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: link...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.12.5)
Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-23-generic x86_64
Distribution: Ubuntu 18.04 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I switched Activities, which caused Latte Dock to switch layouts. Somewhere in
there, KWin may have had a problem. I saw no evidence of KWin crashing, and it
seems to be working fine even now, without pushing the "restart" button that
appears on the notification for these crashes.
- Custom settings of the application:
By default Latte Dock does not change with different Activities, and even after
enablling these non-default settings, it some times acts up and runs both
Activity-spesific layouts at the same time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
