At the beginning when I used trapdoors or went under water the screen would freeze and play the same frames repeatedly and after a while I can't enter my worlds because this bug would happen each time I enter and I cant access options or anything. I would have to go out of mcpe completely and only after several attempts, I'll be able to enter my world until this bug occurs again.
