JW, Could you help check it? It looks like frames dropped due to AV unsync.

I cannot see this problem in Taipei office now... yesterday I hit this problem at home and it was not seen on Chrome. I am going to test it today at home again. The resolution is ~720P, not higher resolution. I should have captured the "stats for nerds".

Close this bug since I have not seen it anymore. Probably there was firefox update downloading in the background.
