I have reported an issue where the game gets rendered from a strange point of view (looks like it’s rendering from 0,0,0 and looking straight down) when returning to the game after it has been in the background.
I started up this app then look away and open another app. After about 1 minute I look back at the app and for about 1 second observe the strange point of view before it starts rendering normally again.
So normally the app looks like this (a cube with different colors for faces)
And then returning to the app it looks like this for about 1 second:
As you can see the purple quad being rendered fully (which is on the bottom) it appears that the cube is being rendered from inside (0,0,0).
