While I was mining in survival mode I came across this weird bug. If you are mining and there is a wall next to you, if you look over to that wall while mining you can see through the wall. I tested this a few times in my world and it happened every time. I don't know if this bug also happens in creative mode because I was only playing in survival. Here are some screenshots also:
