My game is buggy

First I had a clock in a item frame and it appeared as a colorful pixeled square in creative mode in the item frame. I switched my game mode to survival to see what it was. I tried to switch my game back to creative mode but it wasnt working. It said I was in creative mode but I was still in survival mode. This is a bug that NEEDS to be fixed.
