When I logged onto the game the main menu looked like this:

This is the actual main menu with out the menu. And a white thing up in the top left.

Also when I forcefully got on the world was made out of triangles disappearing and what a friend called a nether tree looked like a stair case. Unfortunately When I took the snapshots, they didn't save and I couldn't get back on to prove that this happened. But the main menu is still very important.
