I've got an OpenGL application w/ GLSL shaders, which I have running on a number of systems. However, when I tried to run it on a laptop w/ ATI Mobility Radeon HD 5800 series card my textures seem to show only the lowest mipmap level. The geometry is textured, but w/ a constant color. If I disable shaders, I see the textures fine, so I know the actual texture and coordinate data are good.
Has only else seen this kind of behavior? Is there anything different about the way ATI cards deal w/ texture coordinates in GLSL shaders that I need to be aware of?
