The problem here is that the object gets too large causing the coordinates of the BoundBox to begin to suffer with float precision.
I know that BoundBox is used by the draw_manager for culling test.
@Clément Foucault (fclem), is there anything we can do here? Where should we look in the code?

This is a limitation with absurdly large objects. There is not much we can do.
