  Binary package hint: xserver-xorg-video-ati
  
  HTML5 videos embedded in web pages in a certain way are unusably slow
  with Radeon KMS and cause xorg process to use 100% CPU.
  
  Examples of web pages with videos that cripple Xorg:
  http://www.dailymotion.com/openvideodemo
  http://hacks.mozilla.org/2010/04/account-manager-coming-to-firefox/
  http://videos.videoonwikipedia.org/
  
  There is no crash, and situation is recoverable if web page with video
  is closed and/or video stopped and not in view.
  
  There is an upstream bug report here:
  https://bugs.freedesktop.org/show_bug.cgi?id=27139
  
  There seems to be a problem with how Firefox uses Xrender and how this
  is implemented in the Xorg driver, which causes usage of software
  fallbacks.
  
  I would guess this bug causes many web pages with HTML5 video to become
  unusable in Ubuntu Lucid+Firefox for users of ATI graphics cards with
  radeon-KMS driver. I found no Ubuntu bug report tracking this problem,
  so I'm reporting it now.
  
  I've got an ATI X1400 (r500) card, but this also affects r600 (from
  upstream report).
