This scene
camera {
	location <20,50,-20>
	look_at <0,-5,20>

plane {
	pigment {checker color rgb 2, color rgb y}
	scale 40
	translate -y*20

light_source {
	<0,0,30> color rgb 1
when rendered with AA 0.1, AA depth 1, and sampling method 2, artifacts 
are displayed near the borders between white and green.

The problem is that some "thread blocks" have a noticeably different 
brightness than the neighboring blocks.  I actually noticed this on a 
much more complex scene, and reduced it to this sample.

Increasing the depth or threshold will reduce and eventually eliminate 
these errors.
