Healing brush creates wrong colours

Perhaps since the last update, the healing brush tool is producing funky colours in the edited area. So far it seems to be limited to .CR2 files. Obviously, something is wrong here. The spots remain when I exit the tool, change the zoom, exit and re-enter Develop, exit and re-enter LR, and are also visible in the exported JPG.

 

Help please!

Forgot to mention, it happens with circular or other shapes, feather is 0, opacity is 0. Seem to be only the healing tool, clone works fine.

Issue: The healing brush tool copies colours which do not exist at the source. 

LR Classic 11.1

Win10 Pro 21H2

Perhaps since the last update, the healing brush tool is producing funky colours in the edited area. So far it seems to be limited to .CR2 files. Obviously, something is wrong here. The spots remain when I exit the tool, change the zoom, exit and re-enter Develop, exit and re-enter LR, and are also visible in the exported JPG. It happens with circular or other shapes, feather is 0, opacity is 0. Seem to be only the healing tool, clone works fine. I've rolled back a version and also uninstalled/installed LR with no improvement. It seems to be more prominent on high ISO files, >2500.

 

Some examples below from an ISO 6400 file.

Upload a DNG or the CR2 file with XMP to Dropbox or other site so others can test/duplicate/analyze the issue.

Does this only happen when you select a source in the dark area? Heal might be trying to increase the brightness and saturation of that very noisy area to match the destination area blowing up the noise in the process. Perhaps try moving the source into a more similar in tone area. I do see the same thing happening on very high ISO images when I select a source that is much darker than the destination, but not when the source area is similar to the destination. In the example below, the top left heal area is from the flag itself. The bottom right one was souced in the dark sky area. It is simply increasing the exposure (and shifting the hue) on the very noisy sky area to try to match the color and tone of the flag which causes this effect so I'd say make sure that the source of your healing patch is in the correct area.

Thanks for your answer, I didn't see it until a few days later. You're right, it seems to be a product of the source being in a darker and noisy area. I experimented with this in the examples below. The source in the similar area worked better, but still produced some coloured effects. I tried it in the black area, brown and white areas. Only the white area worked properly, presumeably due to it's brightness. 

Now that I know about it, I can work around it. I don't know if I would agree that the user should account for this, especially considering LR chooses the source automatically. We'll see, perhaps the algorithm could be improved in the future. I've also posted this as a "bug".

Agree. The problem is mainly with Lightroom choosing the wrong source area. This has bugged me for years that it often seems to choose completely inappropriate areas while there are much more logical (same hue, pattern, and brightness) areas closer by.
