I need a more detailed explanation of "After I dig or place a block in there, a portion of it disappears.". Which portion? Can you get a screen shot of the behavior?
What I meant by that, is that when I remove a block into that white area or place something, it returns to its "wanted" state.

You might actually need to delete all of your Minecraft folders and redownload it. You can keep texture pack folders and world saves, but otherwise, no. If that doesn't work, I dunno what to do.
Alright. I'll give it a shot at that later. Thanks for the tip. I'll let you guys know in this post.
