--- Comment #19 from Enno Köster <enno.koester@web.de> ---
I am on 5.4 under arch aswell and found two easy ways to slowly accumulate cpu
usage.

i got two monitors and a panel on each.
When I added the system load widget to both panels I noticed quite high CPU
usage and lagging animations after a while so i hit ctrl+esc and saw the shell
using 33% CPU. I then removed one of the two widgets and the load went down to
17%. Removing the remaining widget removed the remaining constant usage aswell.
Oddly the animations were still lagging even though there was no CPU usage
problem anymore.

Second way was to check for updates with octopi (a pacman frontend).
Since last version it has an animated system tray icon when updates are
available.
After three days of vacation I found my computer nearly unusable with a
plasmashell using 33% CPU and 1.7GB memory. Installing the updates and going
back to the unanimated green tray icon normalized the CPU usage but RAM was
still high and the system stayed unusably slow and laggy so I rebooted.

Today I tried to reproduce this: Checked for updates again, found some, watched
the animated ghost for a while. I could watch the CPU load of the plasma shell
go up from 3% right after checking to 10% after about 10 minutes. Installing
the updates and going back to the unanimated green symbol made it stop right
away. I guess if I waited longer it would have gotten worse. RAM usage went up
about 3MB over time but did not go down in the end.
