What I've found so far:
 - The artifact varies with the image size.  A 960x720 render leaves an
   oblong stain on the upper left vertex.
 - The artifact isn't completely absent with 640x480.  At 640x480, tiny
   white spots appear along the veins of the pentagram, but they are
   absent in a 3.7 render.  I presume that this means you did not put
   them there deliberately, and that they are related to the big heart-
   shaped stain.
 - 3.8 beta 2 does not solve the problem.
