I’m also seeing this issue, sometimes there’s a video glitch, some other it’s only an audio glitch, but both issues results in the audio, video and subtitles to become out of sync.
Stopping and starting the video playback seems to fix the issue for several minutes but it then happens again and again. I’ve done this workaround more than 10 times in a 1h video.
Edit: continued looking at the forum, this issue seems the same as Audio desync after some playback - #9 by dinojanevski
