Your example makes it clear. Thanks. I wonder if there is some confusion of how edges works. As I said, I have seen this setting with completely minimized edges and thought do they really need that? The way to answer that would have been to reset edges to default and then looked for the reversed gradient problem. I was lazy and just thought I would ask instead.
I also see edges set to match the luma setting, but there is no relationship between the two, except by coincidence, so I just wonder if how edges works is really understood.
From now on, I will take the time to remove the edges setting and see if I can find a problem. Then put the setting back and see if it really corrects it.
