SOLVED: Flickering video, maybe subtitle related?

Compared to the iGPU I used to use in my i3-12100, it isn't noticeably any better.  Faster, sure.  But the 12100's iGPU was fast enough to meet my worst case scenario for transcoding for my small user base.  The main reason I got an A380 is for AV1 ENCODING.  Which is also does well, and very quickly.  I can get the same quality at about 15-20% less bit rate compared to HEVC.

For clarification, this is AV1 encoding for storing in my library.  Not for transcoding to AV1.  Jellyfin doesn't do that yet.

I just rebuilt this server, previously I was using intel quicsync but the new system is xeon without that so I added what I had laying round.... which was the radeon.  I have an old nvidia I can repurpose briefly to test with and if that's it I'll just grab a new card.... maybe an arc card.

I appreciate the feedback, thank you
