I am using glGenerateMipmapEXT() with the ARB version of cubemaps to generate the mipmap chain and works on AMD/Nvidia hardware but not Intel. I am having to use
glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_GENERATE_MIPMAP, GL_TRUE);
to get around this bug...
So can anyone here tell me how to contact intel to post this bug?
