Mipmapping issue with textures rendered on to a flat quad (OpenGL)

I am having what seems to be a mipmapping problem when rendering textures on to a flat quad. At some camera positions the object looks fine, but then at others it gets very fuzzy. Unfortunately I don't really have any good leads on this problem but I thought if I posted some pictures other who have experiences other issue might be able to give me some insight.

Could anyone give me any clues about what could be going on here?

It seems that this problem was more of a state issue, the GL_UNPACK_ROW_LENGTH was getting set elsewhere (in this case to 512) but it needed to be 32 for this particular texture so this problem was fixed with a simple (glPixelStorei GL_UNPACK_ROW_LENGTH 32).

Are you sure you are providing the correct mipmaps? Because that looks like you provided corrupt texture data as mipmaps.
