@BigWheel I am one of the people who have been reporting Shield problems, one of which is this: after pausing a video, backspacing 10s, then starting play, the video freezes while the audio continues (eventually syncs back up, but usually just backspacing again fixes it immediately). I believe it happens with videos that have subtitles. I stumbled upon the test ‘nightly’ build you mentioned, thinking that might help. Installed it, played a video with subtitles, and still saw the problem. I can usually reproduce, so let me know if you want logs.
