Hi, I am streaming mkv's from my Jellyfin Windows Server 10.8.12 to my Sony XR-83A90J using the Jellyfin for Android TV app installed via the Play Store.
When using libVLC I get a micro stutter every time a subtitle changes. The video runs perfectly smooth until a subtitle is displayed or changed to a new one. Exactly the second the subtitle is displayed, there is a fraction of a micro-stutter, it's only a fraction of a second, but definitely noticeable.
When I switch to ExoPlayer, this behavior stops, but the subtitles aren't white and in a really weird design, I can show a picture later.
I haven't been able to reproduce this behavior on other devices.
I don't use transcoding. Transcoding is completely disabled for this Jellyfin user, and I verified that Jellyfin is using DirectPlay for the movie.
During playback there is 0 load on the server (because there is no transcoding).
This happens with every movie, not just the one from the example below. Here is one of the smaller mkv's I have, where this issue occurs:

Text #1
Text #2
Any ideas?
