Sometimes when I launch Minecraft, the game fails to load and will blink out random colors. This is fixed by relaunching the game, but my mobile controls (and possibly FOV) are reverted to the default settings because of this. It's annoying to fix my controls and lining them up again, especially if they get reverted again. I'm not sure how to prevent this, or if it's reproducable on command, but it has happened 3 times within the last 2 days.
