As an illustration of the difference between Detail V 3.3.0 and Precision Detail V1.3.3, I've attached a GIF animation of a cropped image area that demonstrates the issue below. The original source image that was used is a 16-bit/channel TIFF with Adobe RGB profile, and was opened in Studio, after which I did 2 separate operations, once with the Detail plugin, and once starting with the original again, with Precision Detail. I've only used the Small Detail control, in this case at an extreme setting of 0.50 to make the issue clear, but it happens at all amount settings, but obviously, also the halos vary in visibility at different amount settings.
The Medium Detail control does a similar thing, although with dark halos around dark features, as does the Large Details control, and obviously for different feature sizes. But the Small Detail control should make the differences already clear enough.
The main issue is, besides the different results between the Plugins, that one of the major strengths of the Detail Plugin (halo-free detail enhancement) are totally absent in the new Studio version, which renders the new plugin pretty much useless, and also much more difficult to use creatively, IMHO.
I'll also raise a technical support request since I assume that this is (I hope) an unintended effect, but not limited to my Win10 PC setup. The reason I first posted it here, was to see if I'm the only one affected.
Source image crop (JPEG version of the Original TIFF):
P.S. It apparently does not happen with the Small/Medium Detail controls, but only with the Large detail control), when I open the attached cropped JPEG version of the source image, but with the full size TIFF source and with a full size JPEG version all 3 controls cause issues, so that starts looking like a Tech support issue indeed.
