I am only experiencing this issue with Firefox. Other browsers work fine. Here are my specs:

  • Firefox 28.0
  • Windows 7 Ultimate, 64-bit
  • Intel HD Graphics (driver up-to-date)

When I view an HTML5 video (e.g. <video>), the playback is incredibly choppy and the video has some corruption/artifacts near the top of the frame.

Flash videos run fine in Firefox.

I've used a screen recorded to capture this issue. Here is the video: https://www.youtube.com/watch?feature=player_detailpage&v=-XAkLHqk3tc

Note: I used the video on Vimeo.com as an example. Vimeo is not the only website serving HTML5 video that is causing problems in my Firefox browser.

One the left is Firefox and on the right is Google Chrome. Google Chrome does not have any issues playing the video.

Any ideas on what is wrong or how to fix this problem?
