When I move in the world, sometimes it happens that the view just moves somewhere. I can not describe it exactly. That's why I made a video. It happens in the video at 0:25 and at 1:15. The problem I had massively in the Minecraft Pre-Release 1 & 2. Pre-Release 3 & 4 I have omitted. At Pre-Release 5, the problem was gone. Unfortunately with the release version the problem is back.
