P: Spot removal removing brush stroke

I agree with Bill, it is very easy to recreate.  It is happening on macOS 1015.7 also.

I won't be at my computer for a few hours so I will send it later. But you can recreate it easy enough. This forum doesn't support sharing raws or xmp files so I don't know how I'm going to do that. How about getting the administrators to add this capability? Should be able to attach a PDF as well. 

• On windows 
• Start with a raw picture that has a large area with not a lot of variation, a sky will do. 
• Overpaint a large area with the adjustment brush setting the ev to - 2. Doesn't have to be that strong just easier to see the effect.
• Switch to the spot removal too. 
• While watching the painted area, click different areas of the image. 
• Sometimes the areas are unpainted with the first click, other times it will take 3 or 4.
• As you continue to click, the unpainted and painted areas will change.
• Actually took me longer to enter this info than for you to recreate the problem. 

USe for Display is on. Image processing is off. 

If I turn it on for image processing, the image doesn't change back to normal when I go out of develop. And if I export...I get an "originals missing for some images" error. Hmm. That might be because I tried to do something else yesterday. Hang on. 

No, exports with the edits correct. When I restart, the edits return as correct. 

That is indeed the case. 

@bill_3305731 can you help us by sharing the image with settings (xmp file) ?

Thanks @i4detail for sharing the image and other details. Can you confirm if the issue resolves if you disable GPU (in Preferences > Performance > Use Graphics Processor option)?

On the other thread for this topic, I provided an example where the image, even when exported, was ruined and another when it was not correct after returning to library. . So definitely more than just a display issue.

Note that, as far as the rest of us have experienced the bug, it is merely a display issue, tied into GPU acceleration. Switch to the library, and your image should look like it should. Yes, it goes back to looking terrible in develop, but the adjustments *should* be there. You could be experiencing something different, so I am using shoulds a lot. 

To get it to display properly in develop, you'll have to restart lightroom. Sorry. 

I have the same issue.  For example, if I use the dehaze brush on a whole sky and then select the spot healing tool to remove a single dust spot on the sky, random chunks of the sky unconnected to the spot that has been removed or the source sky used to heal the spot not only lose the benefit of the dehaze brush effect but actually turn almost white.  Renders a photo unusable.  I am using a brand new iMac with up to date Catalina installed (v10.15.7) and newest (10.0) version of Lightroom Classic.

Here is the image I used in the video I created here:

Along with the XML. I notice that the effect is not as pronounced/non-existent if I only apply one brush/one or two spot removals. I have to get to the fourth or fifth spot removal before it acts up. Basically, as the rendering gets more intensive, the problem gets more pronounced (but then goes away for the sixth spot removal)
