[SOLVED] screen flickering after updating to plasma 6.8

After yesterday's update to plasma 6.8, my up-to-date system flickers everytime I move the mouse (although it's fine just moving the mouse wheel).
Running wayland natively and nouveau drivers with an old nvidia graphic card

echo $XDG_SESSION_TYPE
wayland

lspci -nnk | grep -A3 -i vga
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GM206 [GeForce GTX 960] [10de:1401] (rev a1)
        Subsystem: ASUSTeK Computer Inc. Device [1043:8520]
        Kernel driver in use: nouveau
        Kernel modules: nouveau

Any suggestions?

Thx @seth for the suggestions. It didn't help though.
It's annoying at the moment, but I'm pretty sure a fix is on the way

Have the same problem after update to 6.8. This issue already in kde bugs: https://bugs.kde.org/show_bug.cgi?id=527328. For me, the workaround described there resolved the issue.
