Chrome Error CSS3 3D Transform

I have css to make a flip map on an element in 3d space. It works great, unless you are viewing the page up and down the page where you accidentally get white elements displayed on the page in certain places in Chrome. I added an example image on the facebook tab. In chrome windows, white “drawers” ​​sometimes cover the content. When I comment on the css 3d transform, this does not happen. Here is the fiddle ( http://jsfiddle.net/derekaug/QSEvs/ ) css that makes the 3D material. Unfortunately, I cannot reference the actual tab until it is open.
