Very interesting problem...  Can you post your declarations for the tessellation factor structure (PatchConstants) and your input control point structure (VertexOutput)?  I'm curious to see how they are declared.  Also, have you tried to run the program with the reference device instead of the hardware device?  I recall when I was working on tessellation a while back that there is huge variability from driver to driver, and you may find that the issue is something to do with a problem in that area...

 

I will go back through my notes on tessellation and see if I can find anything related to similar issues, and I'll post here if I am able to find anything.

 

EDIT: One other thing - can you post the attributes of your tessellation setup as well?  For example, the domain, partitioning, etc...  I would also like to take a look at those if possible.
