Since upgrading to 14w25b, I sometimes get a strange glitch where chests are drawn twice, and the draw ordering is incorrect. This only happens when I look at the chests at the correct angle.

I have no idea what triggers this bug. It doesn't happen all the time. You can look at your chests from every angle, and its perfectly fine. Then, I come back later, and notice that everything is messed up if I look at it from the wrong angle. I THINK (not sure though) that this bug happens immediately after either opening or closing a chest, and it affects all chests in the area (probably all chests everywhere).

I do not have the advanced OpenGL options turned on, because, for some reason, that causes chunks to not draw until I get very close to them. (At least it did in a previous snapshot- I haven't checked if this is still the case; either way, that's irrelevant to this bug report)
