trigger plasmashell freeze by moving cursor over launcher items

Plasmashell very often freezes without a reason. I could trigger it quite often by moving the mouse over launcher items (see attached video clip). But now I can't trigger it anymore.

CPU load is quite normal.

KDE is quite unusable because of this.

Possible dubs:
- 373180
- 360892
- 361703

This is the output of plasmashell visible in the video clip:
