    Kernel result differs between HD 5000 and HD 7000 series GPU


      I have an image processing kernel that performs a discrete wavelet transform on a 2D image.


      When I run the kernel on my laptop with mobile HD 5000 series GPU, the result looks correct.

      When I run the same kernel on my desktop with HD 7700 series GPU, there are image artifacts

      at the boundaries of certain wavelet sub bands.


      Same kernel, different result.


      I would like to get to the bottom of this; can anyone suggest a good way of trouble shooting this kind of issue?
