I'm experiencing a problem with Enscape that I've never had before. I think it's new because I never noticed it before. Please see the picture below. I have a weird "banding" problem when I shine the sunlight on this curved surface. It's a simple semicircle with 24 sides. Tried reducing the segment count, copy pasting, drawing from scratch in a brand new file. Checked graphic card updates. Nothing helps. Is this normal? I don't remember ever coming across a problem like this before.
