Biome Crazyness

I was playing minecraft 1.8 singleplayer and I wanted to try the new version out and suddenly something really wrong was happening when I was looking around on the Minecraft World.

I was looking at chunks to load and finally I thought they loaded but...
The biome was constantly changing from Savannah to Desert to Plains....
I added some screenshots to this so you can see what was actually wrong.

1. Start your minecraft up in 1.8.
2. Start a new singleplayer world with no special conditions like flat or Customized.
3. Look around the map and you maybe will find a weird constantly changing biome.
