Hi,
I don't know where I could send this, so I post it here in the hope that a NVidia dev see it.
I have found some bugs in GLSL NVidia's implementation:
-There is a conflict between gl_ClipVertex, gl_TexCoord[X] and varyings.
-faceforward returns a cast warning

In the code linked here, if you uncomment the workaround line in the fragment you will get the correct result (ie: a green triagle). Commenting the gl_ClipVertex in the vertex program also disable the bug.

Bye.

I don't know which OS you're working with, but a while ago I sent a similar GLSL bug report to linux-bugs@nvidia.com. They were very interested in the problem and sent me a reply soon afterwards. They even explicitly requested a compilable and running sourcecode demonstrating the problem.

So if you think you have stumbled upon a real bug in their driver, it would probably be a good idea to tell them.

It works on Windows and Linux.
