I have seen this requested a few times and would like to add in another vote for this feature. I have been having to use HTML video players since I can use CSS to customize the subtitle backgrounds. I really hope MPV could add this as an option because then I could view videos in IINA, which is far better experience. It seems like such a small change, but really helps modernize the look and makes the subtitles blend in seamlessly.
