Description Heiko Tietze 2015-05-13 07:26:35 UTC 
One thread is completely occupied by plasmashell.

Reproducible: Always
Comment 1 Marco Martin 2015-05-14 08:13:59 UTC 
could be useful trying to attach gdb when it does that.
or also, starting to remove applets to see if removing a particular one frees the cpu to see where's the culript

I'm running a couple of conkys plus sys load viewer plasmoid, konversation, kontact, krusader, and Ktp (all minimized to tray).

Right now, plasmashell crashed finally with a bug report. Unfortunately, there are not enough information to report. But I paste the output to https://paste.kde.org/pipjxwzsx

BTW: I do "Sleep (suspend to RAM)" which might be different from other hibernate.
Comment 3 Heiko Tietze 2015-05-16 20:11:47 UTC 
export __GL_YIELD="USLEEP" solves the issue (no high CPU load after suspension).
Comment 4 David Edmundson 2015-08-05 22:49:38 UTC 
/possibly/ fixed in the latest frameworks release.

I fixed a CPU issue with the system load viewer.

could you retest?
Comment 5 Heiko Tietze 2015-08-10 20:28:35 UTC 
Fixed, at least with my current setup (not sure if I changed something but __GL_YIELD is definitely not set). Thanks David!
