Bug ID: 385365
Summary: Kwin crashes after using the default Hot Corner Action
Product: kwin
Version: 5.10.5
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: sibbe.ra...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.10.5)
Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.4-2-MANJARO x86_64
Distribution: "Manjaro Linux"
-- Information about the crash:
Kwin crashes after i used the default Hot-Corner Action for the upper left
Corner of my screen.
- What I was doing when the application crashed:
I had used the default Hot-Corner Mouse-Action in the upper left corner.
Kwin will Crash and recover right after that. No data was lost and Plasma was
still active.
I cant reproduce it every single time. Somtimes multiple tries are needed to
trigger the crash.
The opened Applications are not important for triggering the crash.
- Steps to reproduce:
- Start Plasma desktop and open some Applications
- Use the default Hot-Corner Action for the upper left corner
- it will not crash every time but with a chance of around 50%
System used:
- Manjaro newest Version
- Plasma 5.10.5
- Nvidia 384.90 Drivers
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
