i just tested my 25.10.3 - Goldeye .with a 3050 6gb on oculink and was able to pass through the card on 25.10.3 , this is with an AMD igpu 780M , jellyfin was set to transcode with nvenc set and i set it to point to /dev/dri/renderD129 /renderd128 would have been the 780M for my configuration at least.
im using a hdmi emulatator dummy plug on the 3050
I have a 5060 ti 16gb i could replace it with i could retest with jellyfin if this might help
