Render view displaced on old computers

Hello everyone,
The company I am working for is making some tests in a mexican public school (third world public school).

Our game runs perfect in our machines and some of theirs, but their low end won’t start or will start with the screen displaced to the center.

We are using Unity 5.1.1

Good:

Bad:

The only common thing between the bad ones is that they are using an atom processor, any idea how to fix this?

Solution: DirectX9 + Unity UI need a main camera to center the scene. (We just had to add the main camera)
