Incorrect edge rendering when scaling transparent PSD images placed in Adobe Illustrator

Full reproducible test package (including the PSD) is available here:

Environment
• Adobe Illustrator (latest Creative Cloud version)
• macOS (latest version)
• Fully updated Creative Cloud applications

Summary
We found a reproducible rendering issue affecting transparent raster images placed into Illustrator.
Two files (PSD and TIFF) were created from the exact same source artwork.
They contain:
• identical pixel content
• identical dimensions
• identical transparency
The only difference between them is the file format.

Illustrator renders these files differently when they are placed and scaled.

Steps to reproduce
1 Open the attached example.ai.
2 The document contains two linked versions of the same image:
◦ PSD
◦ TIFF
3 Scale each image to different percentages (for example 90%, 75%, 50% and 25%).
4 Zoom in and inspect the edges.

Actual result
PSD:
• Visible dark edge pixels appear.
• The artifact becomes stronger as the placed image is scaled further away from 100%.

TIFF:
• No artifact.
• Correct edge rendering at every tested scale.

Expected result
All two images should render identically regardless of source file format.

Additional observations
• At 100% placed size, the PSD renders correctly.
• The artifact begins to appear as soon as the placed PSD is scaled.
• The further the scaling deviates from 100%, the stronger the artifact becomes.
• No export is required.
• The issue is already visible immediately inside Illustrator.
• Exported PDF or raster files simply inherit the incorrect rendering already present in Illustrator.
• The issue can be reproduced using only a transparent raster image with 0% feather edges.
• The issue is independent of object color.

Workaround
Replacing the PSD with a transparent TIFF completely eliminates the problem.
Tested successfully with:
• TIFF (None)
• TIFF (LZW)
• TIFF (ZIP)
Attached files
• example.ai
• 6%.psd (Unfortunately the UserVoice attachment system does not allow PSD uploads.)
• 6%LZW.tif
• examplerendering_issue.png

Additional note
During my investigation I found an older Adobe Community discussion titled:
“Black Edges on placed Ai and PSD transparency files”
In that discussion Adobe Principal Scientist Dov Isaacs confirmed that an internal bug report had been filed.
We can still reproduce what appears to be the same issue in the latest Illustrator release.
The attached files provide a much simpler and deterministic reproduction case than the original discussion.
Thank you for your time.
