Actual results:

updating to latest firefox on arch linux broke my hardware acceleration, this worked perfectly fine on firefox 97.0.2. running firefox with MOZ_LOG="PlatformDecoderModule:5" reports following errror

libva info: VA-API version 1.13.0

libva info: User environment variable requested driver 'radeonsi'

libva info: Trying to open /usr/lib/dri/radeonsi_drv_video.so

libva info: Found init function __vaDriverInit_1_13

/usr/share/libdrm/amdgpu.ids: Permission denied

im using gnome on wayland and amdgpu driver

Expected results:

vaapi should be working.

You need to start Firefox with MOZ_DISABLE_RDD_SANDBOX=1 environment variable until bug 1751363 is fixed.

i heard disabling RDD sandbox is a bad thing security wise, i'm currently on wayland and firefox version 98.0.2 , when can i expect to vaapi to work like before 98 update without disabling sanbox .
