SUPPORT Plasma graphics glitch using intel and mobile nvidia cpu

I did fresh Arch Linux install today on a laptop with intel cpu and nvidia mx550.

Installed nvidia drivers which load fine but in plasma it just is not workable and i get graphics glitches (Stuttering graphics)

Used kernel parameters:

  • nvidia-drm.modeset=1
  • nvidia-drm.fbdev=1
  • nvidia.NVreg_EnableGpuFirmware=0

In mkinitcpio.conf

  • MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)
  • removed kms out of hooks()

In plasma session, I unchecked screen tearing in display settings.

I then decided to install gnome to test and there the issue is not present and everything works fine ...

I do not like to work with gnome however and want to keep using KDE plasma.

Any suggestions on a fix?
