the game acts up when the render module is stressed 

its not device related i render 20 chunks per second

i have never seen it break like this even the sky was messed up

basicly set ur render distance to a high number mine is 160

then fall from y=3000 or the place were it supasses ur render distance

and you get this photo bellow

do not put this as duplicate this is a different render bug

bug report MCPE-99880 is when you are rendering far distancing from a high place 

this bug is the effects of getting out of the render distance and rushing back in falling from a high y value
