High CPU usage when desktop has focus, approx. 20%
STEPS TO REPRODUCE
1. Close all program windows to clear desktop
2. I have plasma widget to control cores activivity - on empty desktop the aktivity reaches 18 to 22%
3. Open any program - core activity decrease to 0 to 2%
4. Switch between desktop and program by click: focus on desktop core high; on program low
(4.1. Same when opening kickoff menu bug #484083 reported by me)

Issue exists because of the migrated user profile after migration to Plasma6. New created user does not have this problem anymore. No Plasma6 issue at all.
