So, I was playing on a server for 14w33c with a large biomes world (seed -5979269375298961007) and around (-387, 79, 905) a long strip of chunks started glitching out. This went away when I switched to render distance 10, but came back at render distance 11.
What happens is that the strip of chunks renders as the same chunk, which changes depending on where you are, and where you face.
The only idea I have on why this may have occurred is that the VBO has a problem in it.
I didn't get anything in my output log.
EDIT: I also had use VBOs off, and turning it on stopped the glitch. And my friend on a Mac couldn't replicate the glitch.
