Bug ID: 382618
Summary: High CPU load after login or resume which is fixed by
killing and restarting plasmashell. How to debug?
Product: plasmashell
Version: 5.10.3
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: kdeb...@customcdrom.de
CC: plasma-b...@kde.org
Target Milestone: 1.0

Xorg.0.log
I observed high CPU usage of plasmashell after it starts initially after login.
The problem sometimes / often reappears if the system wakes up from suspend.
(It just got to my mind that both of these situations may be associated with
screen layout reconfigurations, as my machine is a notebook and I reconfigure
the screens for my different work places after login using xrandr in scripts.)
The reason I even noticed it is that this behaviour causes the system fan to
run at significantly higher speed, which is clearly audible. Closer examination
also shows a much more sluggish screen update / more sluggish animations, which
also are fixed by simply killing and restarting the process.
I do not use plasmoids with lots of animations, but I also do not know how to
provide useful debug information. Is there any monitoring tool which shows what
plasmashell is actually doing, or a tool to list all plasmoids currently
running? (I have the impression that there are some plasmoids active which are
not actually displayed on any visible screen, it would be nice to be able to
check this.)
