I did some quick testing and the problem indeed seem to be a driver
issue but I haven't had time to track down exactly what's causing it.
There's nothing we can do until someone have been able to track it down.
You can enter a intel 3d driver bug for this if you want and if we're
lucky someone might be able to help us track this down.
