Describe the issue
I am testing cpu load when I run multiple applications and I have for example gnome-sheel or weston and when I start 1x glmark2-wayland weston cpu load is 10% the 2x glmark2-wayland weston cpu load is 20% the 3x glmark2-wayland weston cpu load is 30% the .. It is much more when I have gnome-shell(mutter) raspberry pi is ranning stable on 1950MHz without cpu governer
I don't understand what weston or mutter is working when they want 10% more cpu load just to properly composite one more window
Regression
Don't now.
