Please use the attached URL! If you use the vertical scrollbar the gap between the red boxes shifts randomly. The same isn't occuring using the vertical scrollbar. It would be great If this problem is solved in future releases of the WebKit Rendering Engine. Because it looks not so good in association with a Javascript based animation framework used to automatically scroll content. BTW: Firefox has the same behaviour. Only Google Chrome drawn the content correctly.
The vertical white lines between each red box begin to "break up" or look like this when scrolling: █ █ █ █ █ █ █ █ █
