I'll mention a couple of things:

On the first level, in the room you enter with the gold key, there's a metal garbage can you can shoot to move towards a hidden panel up on the wall. That garbage can looks glitchy around the bottom of the image.

When I destroy the machine gun emplacement near the subway, the barrel is shown incorrectly. I believe this--and maybe the previous glitch-- may relate to the lack of voxels.
