I am having a small issue with Youtube Embed and Google Chrome. I am using the iframe setting.
The problem is that after the video starts playing and the video control/progress bar fades away, I get flickering on the bottom part of the video.
It displays as if the progress bar is continually moving up and down really fast.
This is visible on the side-black bars of the video (e.g. when displaying a 4:3 video in a 16:9 video player) not on the main video.
Along with that progress bar flickering, I sometimes also see a "thumb" flickering, that is the thumb that appears when the mouse hovers over a particular point on the progress bar.
This is limited to Chrome. I have tested with Firefox 17/18 and IE9 and everything seems to be working fine.
