Occasionally, when I load up a world, a repeat of the same few blocks from random different parts of the world appears and flickers between different small parts of the world. I have had one instance where this issue didn't affect the entire world, the rest of the time, the player appeared to be in it. The issue only resolved itself each time after completely closing and re-opening the game once or twice. the flickering appears to occur randomly, but appears to very highly increase in frequency when the player moves. I have provided screenshot's from the one instance when this didn't affect the entire world.
