on Plasma-Wayland

SUMMARY
I have a two monitor setup, side by side, 24" 1920x1200 screens. I'm using
latest arch linux KDE packages. When I login to a wayland session, it logs in
normally. Then for example I launch konsole application or any other
application, it works on first screen. Then I move the window to 2nd monitor
with my mouse and problems start. When I move the window around in 2nd monitor,
many more konsole window ghosts appear and they dont go away.
STEPS TO REPRODUCE
1. login to plasma-wayland session
2. launch any application, move to 2nd monitor
3. move your window around and see the screen getting filled up with ghosts of
the same window
OBSERVED RESULT
ghosts of same window appears, does not refresh, does not dissapear.
EXPECTED RESULT
Normal behaviour, you can move windows as you wish with no artifacts.
