i checked the specs again. http://oss.sgi.com/projects/ogl-sample/registry/EXT/framebuffer_object.txt and i saw in the examples that they call glGenerateMipmapEXT after creating the textures also. i added this to our code as well and committed to git. could you try if it works?I can't remember if it ever worked properly on my laptop - it works on the mac here, so I'll look into it further...
best, gabor
