Jellyfin: Subtitles cause stuttering when Hardware Encoding enabled using 5700xt.

I can watch movies fine using software encoding but as soon as I enabled HW encoding using my 5700xt I began to experience massive stuttering which made movies unwatchable. I discovered it was actually only occurring when subtitles were enabled by the jellyfin user. Subtitles off no issues. When they are on totally unwatchable but sound is not effected. The video seems to repeat the same sequence for about 10 seconds then move to next sequence a repeat. I've been followed this post as a general guide to get HW encoding working.

So I've enabled AMD driver in Unraid

mkdir /boot/config/modprobe.d 
touch /boot/config/modprobe.d/amdgpu.conf

And edited the /boot/config/go file to include the following lines. 

modprobe amdgpu 
chmod -R 777 /dev/dri

In the jellyfin docker container I added "--device=/dev/dri" in the Extra Parameters field.

In the Jellyfin webui under Dashboard > Playback, I set hardware acceleration to "Video Acceleration API (VAAPI)" and set VA API Device to "/dev/dri/renderD128"

I've tried disabling "Allow subtitle extraction on the fly" and have both enabled disabled "Enable fallback fonts". I've not sure if setting a "Fallback font folder path" would help or even what files to dump in that folder. I've attached my jellyfin logs to confirm the error. Has anyone experienced this issue does anyone know of a good solution? For now I supposed I will be disabling subtitles.
