I'm getting artifacts like this:

when I try to multiply a floating-point texture (using GL_RGB_FLOAT32_APPLE) with an 8 bit/component RGB texture in a fragment shader. The strange thing is I only get these artifacts when the output color is dependent on both textures -- passing through one texture or the other gives the correct results. I'm using a mobility 9700, 10.3.6, and Cg version 1.2.1001 w/ arbfp1
