When subtitles are not burnt in (Web - Player - Burn Subtitles: Automatic), it disappears after ~2 minutes when the movie plays.
If the subtitles are burnt in (Burn Subtitles: Always) there are no problems.
Problem only occures when the movie are transcoded and Automatic are chosen. When i Direct Stream or Direct Play the subtitles are showing fine.
The problem occurred between version 1.8.4 and 1.9.0.
Plex Media Server: Version 22.214.171.12472
Platform: Windows Server 2016
The problem can be seen in all the players i have tried: Web / Plex Media Player / Plex App (Win 10)
Someone else who has the same problem?
