P: Photoshop "Select Subject" excluding row of pixels along canvas bounds

[JasonBV]

Since Photoshop 24.2 (and still in 24.3), the "Select Subject" command incorrectly excludes a row of pixels along all canvas edges that the subject touches. When viewing the mask or moving/removing the subject, the missed pixels remain. There is no "apply effect at canvas bounds" preference available with this command whether processed on the device or in the cloud.

I noticed this issue in 24.3 and had to step back three versions to 24.1.1 to get it to behave properly again.

I received an email from Adobe asking if the reply I received was correct. But why was this moved from desktop bugs? It is a bug.

[kglad]

if it is a bug, it's not related to the cc desktop app.  it's related to photoshop where i moved your post so photoshop experts can address your issue.

[JasonBV]

Okay. I don't remember what steps I took to find myself pointed into that group to report bugs. I am about to write a formal bug report.

[kglad]

ok.

Photoshop version: Windows, 24.3 (and all versions from 24.2 and up)

Issue: The "Select Subject" command (either processing on desktop or in the cloud) excludes the rows of pixels at the edges of the canvas bounds.

Step 1: Open a document with a subject crossing one or more canvas bounds (such as a portrait photo where the person's shoulders run off the bottom edge and/or one or more lower corners)

Step 2: Click on Select > Subject

Expected Result: Selection should include all pixels at the edges of the canvas bounds where the subject overlaps.

Actual Result: Selection does not include the row of pixels at those canvas bounds.

Note: Behavior is correct on Photoshop version 24.1.1 and earlier.

Sorry @JasonBV we could have moved this to bugs for you.

@JasonBV , That selection looks like it might be a feathered selection (curved edges)? Remove all feathering and try again.

[JasonBV]

Not a feathered selection. Just the basic Select > Subject, and no issues on 24.1.1.

@JasonBV have passed this on to the team to investigate.

Hi Cory, this issue still exists in the new Photoshop 25.0.0 even though it was not present in the Beta versions where generative fill/expand were introduced.

Yes I'm seeing this bug as well, it's really annoying as I do all portrait work with backgrounds that need isolating so have to constantly use the quick select tool to take out the offending line of pixels before refining mask. Can confirm not present in previous versions before 24
