Freshly installed KDE Wayland wakeup from Sleep are still half botched

Tried out Wayland on nVidia RTX3090, but sadly it still not ready. Every wake up view are graphically botched. X11 session works. Problem isolated to Wayland sessions. All buttons work if you blindly know which one to press, but icons doesn’t appear, or sometimes reappear. Wallpaper doesn’t load up. Toast messages glitchy.

Articles tried and didn’t work out:

How it looks (every wake up are random one of these; task manager position was changed to vertical by me):

I will update edit post as I go into troubleshooting.

nVidia resume from suspend

sudo nano /etc/modprobe.d/nvidia-power-management.conf

Then add the following line

options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp

Enable the nVidia resume service.
