P: Generative Remove Feedback (Lr Classic & Lr Eco)

@vincenzo_6388: "With each removal operation you leave annoying light halos."

Please attach full-resolution screenshots (not phone pics) of the ENTIRE LR window showing the photo after you've made your selection of the object and then after you've clicked Remove.  We'll then see exactly what's going on and can likely provide an easy solution.

@bergamar to truly match grain in LrC is pretty much impossible.

LrC grain Library is very limited compared to other softwares.

What you can do is apply a Mask with Local Grain over the Gen Remove Area and try to match the image noise/grain.

You can simplyfy the process by creating a Full Image Mask that selects the entire image and apply to all the Image the same Local Grain.

Like this you have a match, in the sense that the grain applied by LrC will be the same everywhere BUT this approach means adding Grain above the one of the RAW. 

DO NOT use Global Grain in the Detail PANEL to match grain

Unfortunately it adds blur we can't control above Grain Size +30.

The Local Grain doesn't add blur so you can keep your orginal sharpness intact, Local Grain is better.

@jerseyjon: "the result ends up moving fragments of the object I'm trying to erase, from one part of the image to another."

@Alan27416038d67j, your screen recording shows you're trying to remove objects from the edge of the photo, and LR is generating some other object as a replacement:

This usually happens when there are pixels beyond the edge that have been cropped out due to Crop, Transform, or Lens Corrections. So undo any of those you've applied and then do the Remove.

Most complaints about Remove are addressed in the article. But if it doesn't help, please attach a full-resolution JPEG exported from the unmodified original photo, so we and Adobe can see the issue in detail. With nearly everyone who has posted a problem photo, we've been able to show how to quickly remove the desired objects.

Have had the exact same issue and just wasted an HOUR trying to redo the edits, only to have all the issues reappear in the photos. PLEASE FIX THIS!

@rivalg: "this tool changed the person position, the where he was looking , etc "
