Using Plex through my PC to Samsung TV. On a few 4k content, subtitles disappear. If I rewind or seek forward or stop & resume (not pause though) it starts showing again, but then disappears In a minute. I noticed this bug only on some 4k movies.

Same thing. Subtitles disappear randomly. Saw it again last night on a 1080p

Super annoying.

Running Server Version 1.18.4.2171

This should have been fixed in 1.18 but definitely is not fixed.
Here is the thread describing it:
