4k video subtitle micro stutters

[oszkar]

I've been having this issue of small stutters each time a subtitle shows up on screen while watching a 4K video. Meaning every few seconds as a new subtitle is loaded on screen, there is a small lag/stutter. This seems to occur on any 4K video I am playing. I am direct playing from a natively installed windows server onto a Fire TV Stick 4K via Wifi. Playback is smooth when subtitles are turned off. Playing the same files over Jellyfin Media Player on my Windows PC seems to not have this issue.

Any idea is appreciated. Let me know if I can provide more info - I do not see anything specific regarding this in the logs. I have an Unraid server that I can also test with but I haven't had a chance to move Jellyfin over yet.
