P: Duplicating floating layer to new doc flattens the layer

[r-bin]

Create a document with only one layer, not background.
Fill the layer with gray, for example.
Take an eraser and wipe a large blurred hole in the center.
Select from the layer menu: Duplicate layer to new file.

The layer is duplicated flattened and, moreover, it is not correctly flattened.







Is this a known issue?

I can reproduce that, the New File is flattened. (21.1.2 on macOS 10.15.3)
This is irrelevant to me personally but I appreciate that the result seems unexpected and unintended.

Hey Christoph and r-bin,
Maybe I'm reading this bug incorrectly, because I'm NOT seeing a problem on Mac 21.1.2.  Let me try to explicitly layout the steps:

1) launch PS and create a new, default-sized document
2) change the Background layer to a regular layer, but you still have a single-layer document
3) fill this single layer with gray
4) erase a hole in the layer
5) click Select > Duplicate Layer and then under Document choose "new" with any file name

I'm seeing two identical single layer files.  And when I copy one onto the other and set the layers as difference, I'm not seeing any issues.  What did I do differently?
Thanks,David

I got the same results you did—then I tested it again only this time I added a transparent layer to the original and it worked fine:

Example 1:


Example 2:


So it looks like you have to have 2 layers in order duplicate your gray layer to a new file.

Your description seems accurate, the color is irrelevant, though. (see screenshots)

It seems the flattening only happens if the duplicated Layer is the lowermost one!

With a Layer behind the duplicated Layer: 

With the duplicated Layer as the lowermost Layer:

This behavior breaks the script for clearing metadata in a saved file.

Duplicate a document with a merge into a new document.
Duplicate a layer from this file to a new document. Saving a file without garbage in metadata and others.

That's weird. I can reproduce it but it looks like a long-standing behavior with an easy workaround. I can log it but it falls into the category of "Doctor it hurts when I do 'x'..." so it would be pretty low priority to tackle.

Oops. I take that back. Looks like it was working at least back in CS6. I'll see if I can track it down to a specific release.

When I follow your video example, my final image has an inside dissolve effect?  V21.1.2  This is with the Duplicate layer over the original and "Difference" Blend mode applied.

This issue was fixed in 21.2.
