Twitch.tv HTML5 player causing video driver crash
Current video card is Radeon HD7800. This issue only emerges when using Firefox to watch videos on the twitch.tv website using the new HTML5 player. At first everything is fine, but there is gradual corruption of the firefox window. Text disappears, graphics corrupt, and eventually the corruption of the graphics leak out into the windows desktop or Aero, causing a video driver crash and recovery. This only happens with the twitch HTML5 player. All other websites work fine. The player also works fine in other browsers. IE9 and chrome were tested. Firefox is at it's most current version, and so are the video drivers.
I've had previous issues with firefox suffering weird, unexplained graphical corruption which were patched out in the new versions. This is the first instance where Firefox caused a complete video driver crash.

I'm getting a Flash player on the half dozen I checked. How did you switch it to HTML5?

Regardless, the current implementation is causing video issues. If I use the old implementation where there is no HTML5 wrapper, the crashing does not occur.
It sounds like Firefox is not fully compatible with some feature of the graphics driver, or that there is a bug somewhere in a video decoding routine that isn't exposed on other sites. But... I really don't know how to track it down or whether any settings changes might work around it without crippling video decoding.
Do you know whether the site uses MP4 H.264 video, or another format? One way to see what is loading is to use the Network Monitor. On the page, press Ctrl+Shift+k to open the web console, then along its top edge click the Network button. Then reload the page to re-download the video files. The network monitor should show the file types as they are retrieved.
Or if a login isn't needed for volunteers to see it, do you want to provide a link to a page where the problem occurs?
This occurs on any given streaming page on twitch.tv website. Any URL "www.twitch.tv/user" which is a valid stream causes this issue. Remote streaming windows produced by twitch on other websites do NOT cause this issue.
