Bug ID: 382551
Summary: plasmashell has high cpu usage
Product: plasmashell
Version: 5.10.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: michael.pols...@gmx.net
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.10.3)
Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.9.37-1-lts x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
don't know specifically.
- Unusual behavior I noticed:
plasmashell eats up all my cpu. when it starts while logging in, it constantly
gets higher. then when I kill plasmashell. the cpu usage goes down to almost
zero. when I then normally start plasmashell again by CRTL+F2 usually the high
cpu usage doesn't come back.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
