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

[Giresharu]

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?

Recently, I finally had the opportunity to switch my system to Ubuntu 24.04.1 LTS, and I reinstalled the Jellyfin container in Docker with hardware acceleration enabled. The same issue can still be triggered. This seems to suggest that the problem is not due to the system itself.
