Texture uv's offest in distance?

I have a uv mapped corridor. The textures look ok up close but in the distance I can see some lines between uv faces. It looks like it hasn't been mapped properly.. but it has.. it looks great in maya and in unity from up close. I have already tried removing mipmapping for the texture.. It improved the look a bit but not enought.. I can still see a lot of lines.. any idea how to fix this?

This is how the line between two uv faces mapped well looks like:
