So I was wanting to test out some of the new render speeds with worlds because I know with the previous versions it would sometimes take a long time for new chunks to load and things like so. I would play with 8 chunks usually, so I loaded up a new world with 8 chunks and when I wanted to increase my chunks thats when the bug happened.

I thought my chunks would increase but that was not the case...

What happened is what you will see in the following images. The first one is when the world was set to 10 chunks and then the second image is at 12 chunks.

Steps to Reproduce:
1. Start a new world.
2. Once its loaded change your render distance higher than what it is.

That should do it, I hope it wouldn't be a difficult bug to fix.

Thanks for your time
