Terrain in third-person is invisible under certain conditions.

In third-person camera, a portion of building near the player becomes invisible from certain locations. Outside terrain is also not visible. Invisible terrain, step back just a tad, and poof, the ground is back! But if the wall is broken, the visual glitch does not occur. See attached screenshots. The structure is a floating box of one-block thick walls. I can recreate the issue consistently in that place.
