Artifact in dark areas on upscaling

Topaz Photo AI Bugs and Issues
1

In dark areas, there is a repeating square artifact when upscaling. I re-ran the same noise/sharpening settings without upscaling, and the artifact was gone. Happy to provide test images upon request. Topaz Photo AI 1.5.0. Ruined an astrophotography enlargement I was having made… It is fairly subtle, but very present on large areas.

I’d call it a bug.

Thanks for reaching out. Please send the following information so I can try to reproduce this.

  1. The original image file.
  2. The processed image.
  3. A screenshot or description of the settings panel so I can see what adjustments were turned on.

Hi!

Done. You’ll see an .rtf file with a few notes. I verified that the issue was present on 15.0 and tied to upscaling the image at 200%.

Thanks,
Bill

Hello,

We just released a fix for the grid issue in v2.1.1. It will require toggling off this Use Neural Engine button in the Upscale filter with Standard and High Fidelity model.

As the note says, turning off Neural Engine will prevent the grid artifact but can increase processing time.

Let us know if you have any questions about this and if it’s working for you. You can update to v2.1.1 in-app or by getting the installer here:
