thanks for the suggestion!
I have square nodes inside of my coroflakes and I've seen a flicker occasionally. this flicker is nothing anyone else would notice, but it has bothered me nevertheless.
I've considered opening up the coroflakes to cut out and replace the pixels that seen to cause me problems. now, I will put my SSC v2 controllers to this purpose FIRST when I lay out the old and new coroflakes this year.
