Bug 503184

SUMMARY
Hey Team, after startup process kwin_wayland is having constantly quite high CPU usage (approx 63% of single 3Ghz core), after killing it compositor(?) restarts with kwin_wayland "idling" at CPU 0-3%

STEPS TO REPRODUCE
1. Login into Plasma

OBSERVED RESULT
With second monitor plugged in via USBC:
approx 63% of single 3Ghz core for process:
/usr/bin/kwin_wayland --wayland-fd 7 --socket wayland-0 --xwayland-fd 8 --xwayland-fd 9 --xwayland-display :1 --xwayland-xauthority /run/user/1000/xauth_rcGssW --xwayland

Without second montior 
approx 13% of single 3Ghz core for process
/usr/bin/kwin_wayland --wayland-fd 7 --socket wayland-0 --xwayland-fd 8 --xwayland-fd 9 --xwayland-display :1 --xwayland-xauthority /run/user/1000/xauth_rcGssW --xwayland
but when I plugin second monitor it jumps to 63%

In both cases, killing it will make it idling (0-3%)


EXPECTED RESULT
kwin_wayland "idling" at CPU 0-3%
