Description Matthias Apitz 2023-09-26 09:28:29 UTC 
SUMMARY
High CPU utilisation of kglobalaccel and Xorg-server when switching between virtual desktops with Ctrl+Tab or Ctrl+F1,
Xorg to ~60%, kglobalaccel to ~20%.


STEPS TO REPRODUCE
1. remove ~/.config and ~/.cache so that plasma creates fresh desktop on next startx
2. configure only: 4 virtual desktops and shortcuts for switching Ctrl+Tab and Ctrl+Fn
3. switch between the virtual desktops some time once per second

OBSERVED RESULT
CPU utilization in top as described, switching stops working or is delayed and afterwards replayed like a movie;


EXPECTED RESULT
Smoothly switch while cycling through the desktops.
