High CPU usage when idle

SUMMARY
After update to KDE Gear 22.08 I have noticed that the CPU usage when idle is significantly higher then before. Both on xserver and wayland. Before update I used to have approx. 0 to 2 % usage when idle, now approx. 8 to 10 %, sometime until 30%.


STEPS TO REPRODUCE
1. Start Plasma desktop and look on ksysguard
