[Bug 89069] Lack of grass in The Talos Principle on radeonsi (native\wine\nine)

I don't understand.

Since setting the unsafe-fp-math attribute just for vertex shaders or just for fragment shaders was both enough to trigger the bug (break grass and hide the GPU faults), I was just wondering if setting that attribute on one of the shader stages somehow also affected the optimization passes and/or codegen for the other shader stages.

Shaders are whole programs. The OpenGL program object has no meaning to gallium drivers.

I'm really not that familiar with the Mesa / Gallium internals, so thanks for clearing that up.
