When I use the spot removal clone brush on a raw image and then convert it to lossy DNG, pink squares appear where the spot removal was applied when the DNG is viewed in LrC. The pink squares are present in JPGs exported from the DNG as shown in the attached file. However, if the DNG is opened in Photoshop, the pink squares do not seem to appear, so I'm not sure if the problem lies in the DNG file, or in LrC's ability to display (and export) these DNGs.
I first noticed this problem 2-3 months ago. It seems pretty consistent and occurs with raw files from multiple cameras.
Please do not use the attach file button. Many members absolutely refuse to open attachments. It is a trust issue. Instead use the insert photo button.
Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.
and then convert it to lossy DNG
do you mean export to dng?
or in library, select convert to dng?
Thanks for the response and advice (the perils of posting for the first time!).
I do mean export to dng (with "Add to this Catalog" checked), sorry for the lack of clarity.

Does this issue apply in both Library module and develop module?
I see nothing in your System Info that might be the issue.
I take it your rig is a laptop?

Not sure on that driver, but check for an update, perhaps on 12/23.2020. Perhaps at laptop mfg support page.
I reported this issue two years ago, but Adobe still has not addressed it. The only solution I've found is moving the Spot Removal spot slightly, which removes the pink cast. Certainly not a good solution!
I suggest adding your comments and Follow at the below report.
Thank you Todd! I came across that thread, but did not notice your post.
The pink squares do go away if the Spot Removal spot is moved. As you say, certainly not a great solution, but it's good to know the images can be recovered if needed.
I did notice your post is from 2 years ago. FWIW I have DNG's with spot removals from as recent as 6 months ago without the pink squares.
The pink squares for me are not present in Library when viewing previews, but once I zoom in they appear. They are always present in Develop.
Thank you both for your help!

I just discovered that using Sync from the original file with 'Check All' selected fixes the lossy DNG pink square Spot Removal issue. Give it a try.
I just made another discovery concerning the pink square Spot Removal issue using LrC 10.3. If you uncheck 'Embed Fast Load Data' in the Export Module> File Settings Spot Removal works properly with no pink squares. So we have another workaround. I also noticed files synced to the Web in LrC 10.3 work properly with no Spot Removal pink squares.
