[Max] Resolved Bugs / Scene scale affecting refraction behavior

Alpha 4, max 2012
I am seeing a strange bug with large scene scale or if an object is far away from the origin, where objects with refractions (in solid mode) seem to miss their backface and render as if they were single sided.
Here's an example:
The car's glass pane is a thin double sided object with a refracting material in solid mode.
There's an object in the scene located 7000 meters away from the camera. Moving the object to somewhere at 2000 meters solves the problem and everything renders fine:
Notice the headlight also rendering differently (correctly).
Scene units are meters, display units too. The pane is around 0.003 meters thick.
I guess it should be easy to reproduce, if not I could try to supply a part of the scene or another example scene.
