I created a new user 'test', did login as 'test', copied my ~guru/.xinitrc
to ~/.xinitrc, started KDE with 'startx' and started on the empty desktop
'Konsole' from the Application launcher and with 'Konsole' the command
'top'. Using the key 'Control_L' a few times, let's say 10 times in 10
seconds, brings the proc Xorg to 60% and kglobalaccel to 20% CPU utilization.

Please let me know, if I could check something.

Thanks
