html5 video in chrome tears hover

When using html5 video in chrome, divs with :hover states will end up tearing. FF 3/4 and IE9 work fine. Just started recently, i开发者_开发知识库t was working fine in chrome maybe a month ago whatever version that was.

Demo of problem: http://jsfiddle.net/5M8nv/5/

Chrome/webkit bug or am i doing something way wrong?

Thanks
