Flatten the stamp image, set blend mode to Multiply, and duplicate the page; adjustments on one will impact the other

[rakunavi]

Hello all,

If an image added as a stamp is flattened, the blend mode is changed to Multiply, and then the page is duplicated, the source and duplicated images will unintentionally interact with each other.

The verification procedure is shown below, please see the video for more details. As usual, the verification is performed after resetting to default settings. The verification uses the image file at the following URL.

1. Add the image as a stamp, either from the Add Image command on the Home tab or by pasting it from the clipboard. It is okay as long as the image is added "as a stamp" anyway.
2. Flatten the image.
3. After activating Edit Objects mode, select the image and from the Format tab, change the blend mode to Multiply.
4. Execute the Duplicate Pages command from the Organize tab.
5. If necessary, open the Thumbnails pane, set the Zoom Level to Fit Page, and the Display Layout to Two Pages.
6. If you change the position or size of an image on one page, the image on the other page will change in tandem. Also, depending on the position, the image on the other page may be temporarily obscured.

For comparison, the following is the result of the same operation except that the blend mode is left at the default setting of Normal. As you can see, changing the position or size of one image does not affect the other.

I report this because it is a bit odd that the behavior changes just because the blend mode is different.

Hoping that the above information will be of some help to you.
Thank you so much for your continued support.

Best regards,

Hello, rakunavi

Thank you for the report, I see the same here and have passed it along for review.

We found that this issue is only temporary, there is an error in memory while performing the duplication and then immediately switching to move the object around, if you save and re-open the file after the duplicate process, these two items will be properly separated.

Nonetheless, this is a bug, which needs fixing, and as such:
#7545: Bug: Duplicate pages - Xform improperly linked

Kind regards,
