Recently in the past few weeks have a reoccurring problem of halation around the edges of mostly skin tones but also other relatively "bright&reflective" surfaces, I have cleaned my dome (outside only) a few times now but doesn't seem to be doing the trick.. Maybe its an internal sensor problem?! Anyone else had this problem and know how to fix it?? Its driving me a little bonkers!!
