(Get the code!)
Can you elaborate what is wrong with the computation? I have seen the bug you reported on some GPUs (mostly old intel GPUs and some AMD GPUs). Newer Intel GPUs (Sandy Bridge I believe) don't show the bug. Neither does NVidia GPUs.
What the computation is doing is matching pixel texture coordinates with the center of texels. Right now I am seeing inconsistent result which I am trying to match to an error in the code or a problem with some drivers.
