At large distances away from spawn (I noticed it at 2,000,000; however, it may occur much earlier), paintings and item frames appear completely dark when facing either south or east, but not north or west. This issue can be remedied by placing non-opaque blocks behind the painting/item frame, although it reverts back if a solid block is returned there.
