I was kind of able to reproduce the issue.

I noticed that the video has been playing very laggy generally on higher resolutions, so I think there's some bug in the ExoPlayer library that causes issues decoding certain streams.

This is certainly not LibreTube's fault though, we don't do any video rendering/decoding ourselves, it's all handled by the ExoPlayer library.
