Well, when I am looking around my house or chest rooms or any other place for that matter, whenever I turn around and look the other way, at the last second I can see the unloaded chunk behind me. I'm not expert so I don't have a clue what it is, but it appears there a quite a few little bugs like this in 1.8 and it's not that big of a deal, but it would be great to see 1.8 polished and in an almost visually perfect state. Maybe we will see this in future versions. I certainly hope so!
