Windows Mixed Reality (WMR), like most room-scale VR systems, sometimes has an issue with relating virtual floor height to actual floor height. The result can sometimes be amusing, but it can also be dangerous to you and your equipment. Seeing the wrong floor height in VR can cause you to lose your balance, or you might bend down to pick something up and smash your controller into your hardwood.

Not only might you find this issue in the WMR Cliff House and games downloaded through the Microsoft Store, you might also see it carry over to time spent in SteamVR. In either case, this fix, if performed from the start of your time in WMR, should carry over to whatever you choose to do in VR.
