Sample video. The artifacts appear at 00:05
Artifacts such as these are very common on this map, they start appearing over a period of several minutes and then disappear for a while, but appear almost never on other maps and then only for a few seconds. The intensity of the artifacts can get much worse than in the video, rendering the game unplayable.
Also, several surfaces on this map, such as dead horses and the interior of burning buildings, are rendered with a weird metal-like texture, but that bug is not a showstopper so I didn't bother to record it.
