It works for about a minute then all the textures bug out. They stretch and a bunch of colours just flash which hurts my eyes. I canโt play on the worlds it happens on. If I exit the game and go back on, it works then the bug happens again. I had to create a new world for until this bug is fixed. Please this is urgent.

My friend fixed this problem by lowering the anti-aliasing in the video settings.
