Bug ID: 371889
Summary: High CPU and memory usage in plasmashell process
Product: plasmashell
Version: 5.7.5
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: hka...@redhat.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
After few hours of work, plasmashell process uses huge amounts of memory (atop:
227M VSLIBS, 2.4G VDATA, 4.8G VSIZE, 392.5M RSIZE) and large amounts of CPU:
80-90% of a single core of i7-6600U.
The issue persists until I kill the process and restart it manually.
Only atypical configuration is the fact I use 3 screens, the widgets/taskbar
are mostly in default configuration (I just change it not to group processes
and the time widget to include seconds and current date).
Besides that, I use only Kontact, Kopete, Konversation, Firefox and Konsole as
far as GUI tools are concerned. System is configured to use X11 modesetting
driver not the intel driver.
