I could give you a screenshot of the debug this week.
For example, we have 3 surfaces, and alternativa calcultate the distance to sort it in a array (a image) and the distance is the color
On normal GPU without the BUG: [index of the surface : value]
[surface 1 : 10, surface 2 : 20, surface 3 : 40]
On a HD3000 with the bug
[surface 1 : 20, surface 2 : 40, surface 3 : 40]
The value of surface2 overflows the value of surface1, the same for surface 3

Just thought I'd add a comment here about my experience with this patch.
I was hoping that it would fix a seemingly closely related problem I'm having on mobile devices with MouseEvent3D events, but not only did it not fix the problem, it broke the windows implementation for me too. So, maybe the patch is ONLY suitable for machines with the driver bug?
