I've found that if you're standing next to a wall on the edge of a chunk, and look around, the chunk "behind" you will not render. While that is what's expected with the new 1.8 rendering system, the problem is that sometimes the chunk behind you can be seen at the edge of your screen, and have it still not be rendered. I've included some screen shots as examples.

As a side note that last screen shot was taken after standing in place with the bug active, and entering the video settings and turning the VBO's off (checking again with no change in the bug) and then back on and taking the last shot.
