When playing Minecraft PE in Gear VR full immersive mode the depth scaling is way off on the X & Y directions vs the Z direction, so height wise things look tall where expected but how far away is way off, for example I have a very large room in my game, playing it normally it looks very large, but in Gear VR immersive mode the room looks very small in comparison, maybe 1/3 to 1/4 the size expected. This also shows on stairs that look extremely steep due to the depth issue. Height scaling also seems somewhat off vs non immersive, no where to the extent of the X & Y direction depth, but things seem a bit shorter than expected.

This is on a Galaxy S7 edge in the consumer edition gear VR.
