Currently working on an experiment: does this bug happen with cobblestone fences?
I still haven't finished it yet though.
You get the suffocating texture when you walk into a block, much like the button bug. (Please relate to it btw)
To recreate:
1. Make a PC village table (a fence and a pressure plate on top)
2. Go to the pressure plate. You will be surrounded with a wood or stone texture.
Plus, it also occured in MCPE 0.15.0
ipad air 2, outdated ios 8.1.2, mcpe 1.0.5, confirmed
It happens with [MCPE-20546] for me when I have Faithful on
