Wayland does not work properly on Nvidia Hardware: It keeps on getting closer but is not there yet, or so I’ve heard. Apparently, the issue is with the proprietary drivers, as noveau works well. But I use AMD, so I’m only working off rumours and opinions here.
Posting this from Hyprland on NVIDIA, arch (btw) and the nvidia-open-dkms driver, but yes, NVIDIA isn’t fully there yet.
