The burn-in subtitles will become semi-transparent when enable hardware acceleration

[Fate]

This issue does not provide any relevant log information, and it only reproduces on my server. And I’ve reinstalled Jellyfin many times.
What should I do now?

Can you elaborate on which system your jellyfin run at and which distro you are using? Kernel Version?

Intel arc is still a bit new so there still could be some driver bugs left.

The kernel version inside both the host and the container are: 
Linux NAS 6.1.0-27-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.115-1 (2024-11-01) x86_64 GNU/Linux

I am now preparing to try installing it directly on Debian without using Docker, to see if there is any difference.
=== ===
After testing, the same situation occurs when directly installed on the host. Maybe I should look for clues related to Intel drivers.

Any chance you could try something newer?

Like ubuntu 24.10 or manjaro with the 6.11 kernel?
