Photoshop 26.1

Windows 19045.3324

 

Step 1: Open a test image

Step 2: Make a small selection with the polyganal lasso tool.

Step 3: Click Generative Fill, then click Generate

 

Expected result: The mask for the resulting Generative Fill layer should match the original selection

 

Actual result: The mask for the resulting Generative Fill layer expands to be larger than the original selection in an octagon shape with feathered edges.

I am also using Lightroom 26.1 and the Generative Remove is showing similar problems.  In the example below, I selected the girl and it expanded to include the road.  In the second example, I selected a dot on the screen (under the square) and it also expanded to include the road.  This is causing me much additional work to Subtract the expandeed regions for every item I want to remove.

I should note that these examples are at 200x zoom and that I get similar but different behavior at other zoom levels and brush sizes.

I have always been impressed with the generative AI in photoshop, but this week I have been working in photoshop and noticed that everytime I make a selection (lasso tool or such) and ask it to generate, the image it generates ends up not fitting the space anymore, and instead ends up much larger and cut off. I am using a mac and am updated the latest updates with both mac and adobe photoshop. This is becoming a huge issue in my design process. Example is attached. I lassoed the area as I usually would and asked it create a straw and icecubes. This is what it renders out, and it does the same every time.

 

Can someone please help?

I'm on 26.11 and this behavior is still ongoing and absolutely a problem.

@Peaceful_curiosity9206 confirm the app version installed:

  • PC: Open Photoshop > Help > About Photoshop
  • Mac: Open Photoshop > Photoshop > About Photoshop

 

If it's 26.0 or before, try restarting your computer.

 

If that doesn't work, try installing the latest version of v25.

 

Note that you can have multiple versions of Photoshop installed so make sure you open the one you intend to use/test. Optionally you can uninstall the version you don't want.

@Kindhearted_Gleam9686 I installed version 26.0.0 but I still have the same problem.

I'm having the same issue and came across this thread. I am trying to remove thin powerlines and my selection is expaned by a huge factor. This is a huge problem because not just the powerlines are remove, but also a big part of the image gets faked.

 

It's shocking that this has been reported in 2024 already and there is still no fix. Maybe we all should pause our subscription until it's fixed.

 

I am using version 26.8.1

Sorry, the quoting system on this platform is terrible and I pasted the wrong user name.
I agree, Generative Fill is important for retouching, too, and should respect selection borders better.

Hi @Sameer K. It's been 7 months. What's the status? When will Adobe address this issue?

Please review all the replies in this thread. This is absolutely NOT "normal and expected behavior" nor is it "consistent behavior across both the older and the latest versions of Photoshop" as incorrectly stated by @Anshul_Saini

 

See this thread about the same issue for additional testimonials, information and examples.

 

I agree that a gen fill patch should blend with adjacent objects and pixels. In fact, gen fill was already doing this well before Adobe decided gen fill selections needed to be expanded and feathered (PS 26.0 and before). Expanding and feathering the precise selections that the user makes causes far more problems than it solves. The results are worse, not better. It's completely unnecessary.

 

Can the gen fill masks be fixed as you suggested? Technically, yes. But you're asking us to literally fix every gen fill mask. This is very time consuming, tedious, and unnecessary. It's an unacceptable "solution".

 

When will Adobe address this problem? Please let me know if you have any questions, need additional information, or would like to discuss this further.
