I was trying out the new Enhance Details function on Lightroom 8.2, and it is working well on some images, but on other images, it creates the new file, but totally messes it up by cutting out a square in one part of the image, and then other green, blue and magenta squares of the same size are placed randomly in other parts of the image.
This doesn't happen on all files (and it isn't consistent as to which files...two shots taken minutes apart with the same camera and lens, and one it won't process correctly, but the other it will. If it messes up on a file, it always messes up in the same way if you try again. It doesn't matter whether GPU processing is enabled or not.
