When double-clicking to full-screen mode, going back with Esc and then calling stop(), the stream stops but it leaves a still picture in the player on IE 11 and Edge 20.
This sometimes also happens when not going to fullscreen, but it is intermittent and I haven't been able to determine what's causing it. This doesn't happen in Chrome 48. I haven't tested it in any other browser.
Fairly esoteric, but maybe something you can fix.

I'm using the player.swf from your distribution.
