@Herbert Moon, neither had I until this time, I stopped when I heard footsteps and was looking closely at the screen, then noticed them? I walked out and back into the manor, and upon leaving, they were gone, upon returning, they were back?

I could post the video somewhere if you want to know what to look for? They are small though, about the size of a full-stop.
