The scaling down method is to reduce "jaggies" on normal shadow lines. This is something else related to unusual shaped blocks or odd corners(like the ones where these artifacts are located). I only brought it up because I haven't seen them in so long, and I thought maybe something had changed or maybe I'm just missing a setting somewhere. I was also under the impression that it was some kind of bug years ago that got squashed.

No biggy right now..I can work around it with subtle placement of a light.
