P: Incorrect cropping of "Define Pattern" in 32-bit mode in some cases.

OK, it did reproduce in LAB. I'll take a look and see what's happening.

I'm trying to follow your steps as stated. If you've left something important out of your steps needed to reproduce the problem, please let us know.

If you're on MacOS (and I think you are): 13.0.4 fixes the licensing bug, 13.0.2 and 13.0.3 fix many other bugs.

The damned forum software converts my PNG from RGB to Bitmap.
The image can still be used, though.
First convert to 8-bit Grayscale then try Define Pattern.
Then convert to 8-bit Lab then try Define Pattern.

8-bit Lab and 8-bit Grayscale problem, too.

IMPORTANT: Use the attached test image as pattern source.

Pattern definition malfunctions in:

8-bit Lab
8-bit Grayscale

Open the attached 450 x 400 pixels 8-bit RGB PNG in Photoshop.
I used versions 13.0.1 and 12.1.1 on OS X 10.6.8..

Convert to 8-bit Lab.
Define Pattern will malfunction, defining only a few columns of the source design.

Convert to 8-bit Grayscale.
Define Pattern will malfunction as above.

Chris,

"you should be on 13.0.4."

I'd use 13.0.4 and risk breaking things that work in 13.0.1 if there was information on the fixes in 13.0.4 or 13.0.3 or 13.0.2 for problems in 13.0.1.

(Retina support is of no interest to me.)

Chris,

"And I still can't reproduce that. In 8 bit it still works."

I specifically wrote "8-bit grayscale" twice, above. It's not clear whether you've tried 8-bit g-r-a-y-s-c-a-l-e.

Still can't reproduce it. And you should be on 13.0.4.

Stan,

"you'll need to be very very specific about the pattern and file."

Look at the screenshot by mcgraphic in the first post of the thread to which I linked. The document view is zoomed to 100% and shows the design being sourced for a pattern. The document tab clearly says 8-bit grayscale. The resulting pattern definition is shown, too. I was able to replicate that document and resulting erroneous pattern definition in a few seconds with no difficulty.

"be specific about the exact Photoshop version you have, and which OS you're running"

The error occurs consistently (i.e. at every attempt) in Photoshop 13.0.1 and 12.1.1 on OS X 10.6.8.

Conroy, I don't think your forum post has enough specifics. You're obviously having a problem, but you'll need to be very very specific about the pattern and file. It's best to create a file with the problematic pattern and upload it somewhere so everyone can test.

Also be specific about the exact Photoshop version you have, and which OS you're running on OS X or Windows (also the exact version of OS X or Windows you have).

I'm not an Adobe employee, but I'm a developer, and so I know some of these problems can get very specific depending on your setup.
