Problem refresh with new kde6 on opensuse

Hello,

I switched to KDE 6 Wayland with my Tumbleweed openSUSE distribution. Since then, I’ve been experiencing a significant problem with windows. It appears that when a window rapidly repaints with numerous changes, it seems to clip and refresh slowly.

I have 2 screen at 60Hz one with a resolution of 36402100 (4k) and one with a resolution of 19201200 with a nvidia card and proprietary drivers.

It worked finger in the noose on kde5 and Xorg.

This is annoying, does any one have the same problem ? do you have a solution ?
