I was planning on starting a video series for twitch.tv, but when I loaded the world, part of the map was loading wierd. When I noticed the chunk problems, I thought the world was corrupted, but when I used the same seed for a different world, the problem showed up. I then made a completely new world and I still had the problem. The bug is only visible for if the render distance for the game is over 5.

I have a video about this
