Bug ID: 365215
Summary: Animated tray icons cause plasmashell to use up a lot
of CPU time
Product: plasmashell
Version: 5.6.5
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: System Tray
Assignee: plasma-b...@kde.org
Reporter: kdeb...@fratti.ch
Should a tray icon be animated, e.g. the quassel icon when receiving a
highlight, or the Skype icon while logging in, the "plasmashell" process takes
up a good 15% of the total CPU time (25% being maximum for one core), with
additional CPU time used by Xorg as well. (So it's probably busy sending tons
of drawing commands)
This is pretty bad when I receive a quassel highlight while I'm not looking,
and then notice that plasmashell was busy draining my battery doing
god-knows-what to re-render that small area on the screen.
Reproducible: Always
Steps to Reproduce:
1. Have a tray icon which is animated
2. Watch plasmashell shoot up in CPU usage
