Missing DRM render device on Wayland
Firefox 110.0.1 KWin 5.27.2 NVIDIA driver 525.89.02 Arch Linux RTX 3050, no integrated graphics on my system whatsoever
Everything is working okay in X11 but when I switch to Wayland, Firefox can't find the DRM render device and therefore doesn't use nvidia-vaapi-driver. I'm using the most recent commit of nvidia-vaapi-driver built with open-gpu-kernel-modules as of the time I'm writing this. I manually built nvidia-vaapi-driver following the instructions from this repo, not using any AUR packages.
/etc/environment: MOZ_ENABLE_WAYLAND=1 EGL_PLATFORM=wayland MOZ_DISABLE_RDD_SANDBOX=1 NVD_BACKEND=direct LIBVA_DRIVER_NAME=nvidia GBM_BACKEND=nvidia-drm
Firefox settings: media.ffmpeg.vaapi.enabled = true media.rdd-ffmpeg.enabled = true gfx.x11-egl.force-enabled = true
Firefox logs: ❯ MOZ_LOG="PlatformDecoderModule:5,Dmabuf:5" NVD_LOG=1 firefox [Parent 30714: Main Thread]: D/Dmabuf wl_drm is available. [Parent 30714: Main Thread]: D/Dmabuf zwp_linux_dmabuf_v1 is available. [Parent 30714: Main Thread]: D/Dmabuf We're missing DRM render device!

Please let me know if there's anything I'm missing or anything I can provide to help with debugging.
Manually specifying the DRM render device with MOZ_DRM_DEVICE=/dev/dri/renderD128 enables nvidia-vaapi-driver to work on Wayland, so it seems the issue specifically is with enumerating render devices.
I also have this issue on Wayland and X11 even with my Intel HD graphics (i915).
