Describe the bug

System (please complete the following information):

  • OS: Alpine
  • Virtualization: Docker
  • Clients: Browser
  • Browser: Firefox
  • Jellyfin Version: 10.5.5
  • Playback: n/a
  • Installed Plugins: none
  • Reverse Proxy: none
  • Base URL: none
  • Networking: Host
  • Storage: local

To Reproduce

I have this image set as the FRONT_COVER for some mp3 files through eyed3 (though it also still happens when I run it through ffmpeg -> png, export from gimp, etc). But, when I look at the thumbnail, it shows
this instead. However, it doesn't do that for folder thumbnails.

Expected behavior

Expected there not to be a green square over the thumbnail image, I guess.

Logs

n/a

Screenshots
