Description Marc Haber 2016-07-28 12:02:31 UTC

Hi,

when I have an analog clock on my desktop, after a while, plasmashell's CPU usage goes up to 14 % of a core and stays there. Removing the plasmoid reduces plasmashell's CPU usage to zero immediately.

Analog Clock is shiny and nice, but not so shiny and nice to justify it taking that much CPU. I find it particularly interesting that the CPU usage only goes up after a while and not immedately.

Greetings
Marc


Reproducible: Always

Do you have seconds enabled?

Thanks, but this isn't very helpful on it's own, so I'm going to close this, but please see the linked reports.

We have multiple high CPU bugs, some caused by us, some not, some fixed, some unknown. It's hard to say what the cause of each one is, and bug reports get convuluted.

I've made a list of some of the bigger more specific ones:

For high CPU caused by reloading icons over the SNI protocols see:
356479

For high CPU caused by infinite spurious X events see:
373368

For others, search other bug reports here. 
Hopefully your cause will be fixed in the next or future releases.
