As of this week's patch I am now seeing red pixel blotches in highlight areas.
These areas were not red prior to the patch and nothing else has changed on my system.
This seems to be some kind of highlight warning. I can save my pic to jpg or other formats and the red is not present. I can reduce the highlights and the red areas deminish with reduction.
Adobe, if this is some sort of warning thing you added, GET RID OF IT!
