System defaults to LLVMPIPE on Kubuntu 22.04 w/ Wayland

Recently installed wayland on my system
kernel version: x86_64 Linux 5.15.0-83-generic

Despite the most recent drivers installed it defaults back to llvmpipe

Seems like the issue is that X11 is starting before Wayland? Possible solution(?): NVIDIA - ArchWiki Please help me to implement this on Kubuntu

nvidia-drm.modeset is already set to 1, it has no effect.

Ok, I fixed it. Apparently libnvidia-egl-wayland1 was missing. This was what was causing the issue.
It works now but it is barely usable. Every animation LAGS and there is some very weird ghosting and stuttering going on. (Words keep disappearing and reappearing as I’m typing this).

What does one need to write here to get the attention of an actual dev?

libnvidia-egl-wayland1 installation solved it for me on with the following system:
