Unfortunately the GPU branch is quite buggy. It's actually an issue with pygpu. I've tried updating it a few months ago to the latest version, but I still ran into crashes. This is the issue I created:

I think pyshader is responsible for replacing the clamp with its own implementation. You can find the function definition here:
