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:

Are you using X server 1.19?
Comment 2 sedrubal 2017-01-11 00:14:19 UTC
Yes:

- Xorg 1.19.0
- Plasmashell 5.8.5
- Fedora 25

And I figured out that switching to another virtual console and switching back unfreezes plasmashell like "PC LX" mentioned in bug 373180 so this seems to be a dup of https://bugs.kde.org/show_bug.cgi?id=373180
