P: Gen Remove now changes elements outside the painted mask

15.4.1 is out now, did anything changed? Has anyone tested it? I’m stuck on v14.4 for almost a year now because it’s one of the most used features for me as professional photographer. 

At this point, it seems to me that they made it worse on purpose in order to push users toward Photoshop's built-in tools, which they can monetize

Hi everyone, i found out this thread after have updated today Lightroom Mobile for my Samsung S26 Phone.

Last week the ai generative eraser was a beast, it could even remove isolated pixels by using a single tap by selecting a brush size of 4. Results were just incredible, not only 100% undetectable but you could also rebuild fully complex networks of veins and material.

Since this update, i have the same problem than all of you, the results are a mess and let traces that are damn visible !

My incoming business (incredible paintings in big size) has a complex pipeline in which ai inpainting plays a very important role.

So did anyone experiment a very recent change in Lightroom Mobile (last week all was perfect) that would confirm all the mess i see here on my screen ?

If things do not change it's going to kill all my workflow and that would ruin almost 1 year of work with ai to output amazing high definition and perfect paintings in big size (i use topaz suite too).

Even though Adobe has marked this issue as a “bug” and said five months ago that a fix would arrive “soon”, there’s been no announcement of a released fix:

Also, for reference by future readers, it was LR 14.5 that introduced this undesired behavior.

In version 14, this retouching tool was by far the best thing Adobe had to offer.

The generative removal tool is still imprecise even in version 15.2. Since version 15.x, the tool also takes areas outside the selected region into account and generates incorrect results.
Previously, it was accurate down to the pixel.

I will probably have to switch back to version 14 once again.

Still experiencing changes outside the painted mask in Camera Raw 18.2.1 + old version (17.3.1) now blocked from Generative AI

Environment: Camera Raw 18.2.1 (via Adobe Bridge) Windows 11

Issue 1 — Generative Remove still modifies areas outside the selection in 18.2.1

When I use the Remove tool with "Use Generative AI" enabled in Camera Raw 18.2.1, the tool still modifies pixels outside my painted mask. In version 17.3.1, the tool correctly changed only the selected area. This was listed as fixed in 18.1.1, but the problem persists in 18.2.1 for me.

Issue 2 — Old version (17.3.1) no longer works for Generative AI

I continued using Camera Raw 17.3.1 because it respected mask boundaries. However, as of March 9, 2026, the Generative Remove feature now returns an error ("問題が発生しました" / "Something went wrong"). The server-side API appears to have been deprecated, forcing users to upgrade to a version where the mask-boundary issue exists.

Impact: This is critical for my professional workflow. I use Bridge + Camera Raw to batch-process photos and rely on precise mask-only removal. The current behavior—where surrounding areas (faces, hair, skin) are unpredictably altered—makes the tool unusable for portrait and product work.

Request: Please provide an option or setting to strictly limit Generative Remove changes to the painted mask area only, with no modification of surrounding pixels. Alternatively, restore the behavior of version 17.3.1 where this worked correctly.

Thank you.
