Bug ID: 413016
Summary: Plasma crashes when switching windows
Product: plasmashell
Version: 5.16.5
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: w...@wian.co.za
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.16.5)
Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 5.0.0-31-generic x86_64
Distribution: KDE neon User Edition 5.16
-- Information about the crash:
- What I was doing when the application crashed:
I scrolled the mouse wheel on the task manager to scroll between windows (task
manager set to windows on screen & display). I also just got a crash while
typing this when I clicked on "configure panel". This also happens when I
Alt+Tab through my windows. There is usually a delay, then the window
decorations & panels disappear and then they restart.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
