This file has a fixed position div (Blue) that incorrectly scrolls with the page content. IF you remove the webkit-transform from the body element, the blue div no longer scrolls.

Applying a webkit-transform to the body breaks the positioning of all fixed positioned elements. If you remove the webkit-transform from the body, fixed positioned content is then properly positioned and no longer scrolls with the page content.

The attached file provides an example.
