Comment 3 for bug 1055126

I was able to successfully reproduce this. It's an issue that pops up only when the screen resolution is high (above 1440:900, it's very obvious with my 1920:1080) and the dash is set to fullscreen. In my case, it happened on Intel GPU, but since it's more of a compiz performance issue, it should be reproducible on amd and nvidia systems too.
