I've removed now ~/.config and ~/.cache so plasma created a new fresh
desktop on the next 'startx'. I did the following config changes after
the desktop was up:

- configured 4 virtual desktops
- Ctrl+TAB to cycle forward between them
- Shift+Ctrl+TAB to cycle backward
- Ctrl+F1 ... to jump to desktop 1 ...

With this the problem is again visible: kglobalaccel5 and Xorg process
CPU utilisation goes up when switching and when I switch to fast,
it does not even switch anymore and later replays fast the movement.

What next to check? File a PR?
