At least with vtt and srt, the chunk of text displayed is explicitly associated with a chunk of time, so something like that really shouldn't be happening. Maybe there is some sort of subtitle-writing on the fly like what is sometimes done with transcoding video, but that would be really strange for a plaintext format that is so light compared to the video and audio coming with it.

I don't disagree, yet here we are. It's got race condition vibes.

I don't know if it's related to the TV OS (LG WebOS in our case) but I guess that would be the common factor since it happens across multiple apps and languages.

Anyway, it's quirky and occasionally annoying, but that's about it. :)
