It's weird to see Korean subtitles

You’re making good use of it. Atv jellyfin.

I think there’s a problem. Korean Subtitles line split.

In Nplayer, the line split of the Korean subtitles appears on the screen as soon as it is made.

But in Atv jellyfin, The player splits randomly.

I think this happens only in Korean subtitles.

It works well on the jellyfin web.

Could you please check that for me?
