    This is a pretty weird issue I am experiencing. 

    Setup:
    Ubuntu bare metal 24.04 LTS
    JF 10.10.7 (this issue has been occurring since at least 10.9.x though it is fairly rare)
    HP Elitedesk 1L mini PC
    7500T (can handle 3 consecutive 1080p transcodes without missing frames) 
    16gb RAM
    2TB SSD (SMART is ok)
    All playback devices are on the local network and all wired with ethernet

    After a period of time files seem to be having issues with Jellyfin.
    An individual file will play many times over and over then one day they go stuttery like they are dropping around 50% of their frames. 
    The playback info states 0 dropped frames and 0 corrupted frames.
    Once the file goes stuttery from that point forward all attempts to play it will be stuttery regardless of the streaming device.
    Lowering the playback quality to force a transcode stops the stuttering.
    After forcing the transcode, changing back to the native bitrate to use direct play the stuttering restarts.

    This is not a hardware power issue. I can play a high bitrate 4k file at 20mbit perfectly fine right after playing a stuttery file 1080p file.
    The issue occurs on LG OS app, Google Streamer app and Firefox web browser playback.

    I can move the file off my JF server and play it locally on my PC with VLC with no issues either, so it's not the actual file being corrupted either.
    Running BTOP when playing the file shows no issues, no temp issues, basically idling as you would expect.
    It is like some part of Jellyfin is getting corrupted? Maybe some database or something?

    I could try rebuilding the library but i'd rather not as there was a lot of manual work I had to do with identifying. 

    Jellyfin settings are basically stock.

    The files that are having issues are Shrek and Moana, but I cannot see any errors in there personally.

    I have attached some logs.
