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?
