If you trying to crash the world (example: exploding a large amount tnt), the world started glitchy where it turn on the hide gui (the hand/held item still visible), mobs/entity get invisible, and the water gets glitched. However when you trying to press back/menu button, the selection is not visible too, if you're lucky to press "Quit to title", the screen becomes an empty green screen (where the tittle screen was rendered incorrectly).
