Subtitle-related transcoding causes impossible stuttering

Actually, no. 5.3.1 hasn’t fixed anything. This (unnecessary!) transcoding starts to buffer like crazy every time one rewinds or fast forwards, shows menu(s) or resumes from title screen. Pausing seems safe, but I haven’t tested it too thoroughly.

Possibly related to LG webOS Plex 3.60.1 Buffering Problem or LG TV App Transcoding SRTs.

This has clearly nothing to do with the stress the transcoding incurs (even forgetting it’s not needed in the first place), but a bug in the app/server/whatever.
