Description Philipp A. 2019-06-21 07:56:54 UTC

Having the application dashboard on my desktop/panel or starting it with

plasmawindowed org.kde.plasma.kickerdash

… causes ~70% CPU load from the processes kactivitymanagerd and plasmashell on changing cores. With “changing”, I mean that every half second or so, another core spins up.

This behavior continues after I remove the application dashboard or close the plasmawindowed window.

Oh, and that makes plasmashell super unresponsive. Hover effects have more than a second delay, and processing notifications also takes a while (they appear unresponsively and need time to move to their intended position and become responsive)

Seems like it was resolved
