Chunks not rendering properly at high render distances

Expected normal chunk loading at render distances of 11 chunks or higher.

Some chunks didn't display properly, and loaded the wrong graphics. Graphics change if cursor is moved around where they are displayed.
Effect may be in different locations if render distance is changed.

To reproduce:

1: Increase render distance to 11+chunks, effect has been seen at 10, but only once

2: Exit settings, look around until you see the glitch.

3: Move mouse around in area to produce different graphics.
