when switching between virtual desktops

OS: FreeBSD
Status: REPORTED
Severity: major

Assignee: kwin-bugs-n...@kde.org

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.
