When playing an MKV with embedded subtitles, after a short time of watching, the subtitles stop being displayed.

Switching from Forced SRT to SRT, or back again, seems to make the subs show again for a little while, but then they stop appearing again.

Running latest (1.9.4.4325) version on Windows 10, and playback on MacOS web player (3.20.7).

Is anyone else experiencing this issue?
