I have encountered this as well. Unlike the chunk loading issues in previous versions (where the chunks would all load, but in the wrong order) these chunks never load until you get within ~30m of them or force a rerender with F3+A.
Switching from "OpenGL: Fancy" to "OpenGL: Fast" seems to prevent or greatly minimize this bug.
