  Difference in noise3d in beta2?

This is directly from isocacti.pov (everything but the relevant parts
taken out). If you render it with 3.7beta2 you'll notice that there
are big plateaus in the isosurface which do not appear with 3.6.
What is causing the difference?


#include "functions.inc"

#declare CamLoc = < 5, 10,-10>;
camera {
	location CamLoc
	up y*image_height right x*image_width
	angle 45
	look_at <0, 0, 0>
}

light_source {<-20, 30, -30>*3 color 1.5}

#declare Ground =
isosurface {
	function {y - f_snoise3d(x/7, 0, z/2)*0.5}
	threshold 0
	max_gradient 1.1
	contained_by {box {<-100,-3,-100>, < 100, 1, 100>}}

	texture {
		pigment {color rgb < 1, 0.9, 0.65>}
	}
}
object {Ground}
