 Actually...not that strange. I am guessing this has something to do with depth peeling being used with offscreen context (which is created for saving images). Depth peeling is being used since the box widget reports that it has translucent panels. Easy fix would be to disable translucency.

 When the faces are not selected, their opacity is 0. In
reality when opacity is 0, it should not affect the consideration if depth
peeling is used since it doesn't really matter. However, vtkActor::GetIsOpaque()
return false when opacity is 0, and we end up using depth peeling. The more
complete fix would need some change to the actor API. For now, simply not
considering the face into translucency check unless it is selected does the
trick.
