Bug ID: 372274
Summary: Plasmashell High CPU usage
Product: plasmashell
Version: 5.8.3
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: gustavo.alma...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.8.3)
Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.4.30-1-MANJARO x86_64
Distribution: "Manjaro Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Sometimes the plasmashell starts having high CPU usage between 50 - 90%, I
couldn't spot what really triggers this behavior, I noticed this downloading
torrents (using qBitTorrent) or big files (like games from steam), and today
using unetbootin. All I do is stop the service and start it again, then it runs
normaly untill restart.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
