plasmashell process strace
This is a short strace capture of the plasmashell process which needed 100% of one cpu core ...
I do not have a CPU widget running ... Can confirm: seems to be caused by hovering over something that provides a tooltip. For example the clipboard. Or a battery monitor. If you taunt the shell a bit like this, it will also cause the plasma panel to start flickering. Created attachment 94603 [details]
Screenshot of the issue
Displays ksysguard CPU monitor while hovering over the clipboard icon in the systray.

Attached the requested file. It isn't a widget which is causing that ... Same problem here. I've tried debugging but I'm out of ideas how to proceed further. What I found so far: * top reports currently 76% cpu usage for plasmashell and 35% for X * sysprof cannot pinpoint the exact function which causes the high load (no map) but the kernel is doing a lot of copying. So I think plasmashell is repeatedly repainting something. * as comment 3 said it seems related to hovering: if I hover some task it often happens that other windows stay transparent after the mouse leaves the entry. I have to re-hover-and-leave the entry (sometimes a few times) to see all windows again. Let me know if I can do anything to help solving this problem (testing patches, running some kind of debug-sofware). Same here. The problem exists from longer time. It is making KDE less responsible (scrolling, moving windows, etc.). *** This bug has been marked as a duplicate of bug 356479 *** |
