Sometimes i get a broken background in Chrome. I do not get this error with any other browser.

This is the simple CSS line responsible of the background color of body:

body 
{
   background: black;
   color: white;
   font-family: Chaparral Pro, lucida grande, verdana, sans-serif;
}

This is exactly how i get this problem. I click a link included in an gmail's email and i get:

I refresh the page and the background is colored complete.

Does ayone knows about this problem?
