html5 video issue - buttons appear as white squares in chrome

Please review the link: http://www.useboom.com/

The video in home page works fine in other browsers but in chrome the Play and Volume buttons have a white square on t开发者_StackOverflowop.

The buttons were fine and visible before, we've been deleting unused files and suddenly started to appear this way.

I don't know what is the problem!

I had the same problem with Chrome and worked out it is caused by styling "input" without specifying which one exactly i.e.

input {
background-color:white;
}

Using:

#my_div input {
background-color:white;
}

solves the problem. Hope this helps.
