P: Spot removal removing brush stroke

I am having this same problem.

Using Mac version of Adobe Lightroom Classic v10.0

With GPU turned off everything works fine; instant spot heal and local adjustments. No blackouts. 27 in., 2460x1440 resolution display, Win 10.

I had the same thing happen yesterday; spot removal in a previously brushed area caused part of the brushwork to disappear, but then removing a second spot caused it to come back. Also several seconds wait for each spot correction to be applied, sometimes with display blackout in the interval. Today I will try working with GPU turned off. Windows 10, LrC 10.

Anthony, 

I guess I don't understand what you want in addition to what I already supplied. Let me know and I'll do it sometime on Thursday. 

I would add that since I use both LR and PS (along with others) in my workflow. I save all of my spot removal for PS. It is much more reliable and flexible. I have a brush preset that I use in Quick Mask mode utilizing content-aware. With it, I can remove any spots, most items, changing sizes on the fly as well as removing long spots or items, overhead wires, cracks in sidewalks, the dividing crease between cement blocks, etc.

I've tried reproducing this problem and have been unable to get LrC 10 to misbehave.

Bill, can you provide more detailed steps with screen shots of brush work and spot removal?

Update:

1. exported image 2 as a 4K jpeg
2. imported jpeg 
3. performance restored, instantaneous spot removal
4. excellent results

So the trick (technique) until we get a fix:

1. perform all edits except spot removal
2. export image as a jpeg
3. import
4. remove spots 

Overview

1. very slow, about 2-3 seconds per spot vs instantaneous on V9.4 
2. like was reported for MacOS users, removing a spot undoes a brush stroke

I've been trying to recreate the MacOS problem on Windows and finally did it by accident. This is a freshly imported image. Below are screen captures:

1. before brush 
   
   
   
   
   
   
2. after brush
   
   
   
   
   
   
3. after removing one spot 
   
   
   
   
   Depending on the spot, different areas of the bag are affected. 

Just FYI, this is a velvet bag for a Sony headset that could find lint in a NASA clean room. 

Tested and confirmed this on my end, too. Win 10 - I haven't tested thoroughly but seeing it when Exposure and/ or Shadows is used in the brush

Thanks for the information. We've logged a bug to investigate.
