stamp tool will not change pixels in region of layer that was part of previously crop-gel-expanded

[WmLake]

MacOS 18.1 , Photoshop Classic 26.0.0 11/16/24

Using stamp tool on a layer that filled the canvas, as pixels changed, the pixel area that was the result of a generative-expand-crop function previously, would not change. The stamp tool would not work on this region of pixels.

Previously, I had expanded the cropped region to a larger area using the crop-generative-expand. Throughout my edit session, I would periodically merge visible layers. I was down to a single visible layer and was using stamp tool when the region of pixels uniquely in the epand area were not affected by the stamp tool. I checked to confirm that those pixels were not part of another layer that, while marked invisible, was somehow visible.

The reason I had been merging layers together, sacrificing some control of the image, was because I was having a lot of trouble with generative fills when multiple layers affected the content. Often, I would get "service not available" or long (30 sec-2 mins) to get results. 

The canvas was 24"wx12"h @300ppi

This was my first use of the gen-fill features. 

I should point out that there were lots of other bugs in this session. One time all the layers, without keystroke, reduced themselves to 2 layers that were very small (2"x1")regions of zoomed-in content. I had to reopen the doc.

Hi @WmLake,

The behavior you’re describing with the Stamp Tool not affecting the expanded region of pixels from a generative crop-expand action could be related to multiple reasons. Here are a few steps to try and resolve this:

1.  Right-click the layer and select Rasterize Layer to ensure all pixels can be freely modified.

2. Verify that the layer is fully visible and unlocked. Also, ensure that the expanded region isn’t accidentally marked as a protected area.

3. Double-check the Stamp Tool's settings (such as Opacity, Flow, and Aligned mode). Lower settings or non-aligned sources could cause it to appear ineffective.

If the issue persists, please share a screen recording of the behavior and a sample file. This will help identify if it’s a specific bug with the generative tools or another aspect of the workflow.

Let me know how it goes!

Best,
