I recently installed Kodi 21 on my Sony TV and found that subtitles are not displaying on the video's black bars but on the image. Even when I set the subtitle position to the bottom of the screen in the player settings, it doesn't work. However, when I reinstalled Kodi 19.5, the subtitles could display on the black bars. My subtitle format is SUP. How can I make Kodi 21 display subtitles on the black bars of the video?

I believe if you set Kodi 21 to manual you might get the external .srt in the black area or at least movable.

What's the mediainfo of the video?
A sup subtitle is image based and cannot be moved, unlike text-based subs.

Thank you, is this a bug in Kodi 21? Is there a current workaround?

[bluesea]

Keep the current Kodi and don't upgrade until the bug is fixed，You'll also need to provide debuglogs for Kodi 19.5 and Kodi 21

I tried a few more times in kodi 21 and found that after unchecking dolby vision in player setting>videos>allowed HDR dynamic metadata formats, the subtitles can be displayed in the black bar, but dolby vision cannot be turned on when playing the movie.
