This isn't a game breaking bug, but it's anoying. So when i use mouse and keyboard to play minecraft on my PS4 everything works fine, but when i move for example my cursor down while exiting the inventory from somthing ex. chest, furnace, etc, my player camera will go directly to look down as far it can. Its the same for moving it up. It doesn't happen when moving it side to side. It doesn't matter if you move the cursor slow or fast it will end up looking straight up or down. This makes fill like i lose the control of the game for a moment and its worse when i need to exit the inventry fast because i'm been atacked.
