This one bugs me a lot. I found some pixels that are in the scene, but are not in the view port, but I can't make any sens from them. Dose it have anything to do with printer color dot steganography?
Only submit the second part and submit it as-is (no changes in lower/upper case and with the spelling mistake). Make sure you found the right solution though (which should be very clear when you found it).
You can PM me if you want to check that you are on the right track.
