Can you tell me which Photoshop plugin you are using in order to get a better understanding of the workflow you use that receives these edits:

  • File > Automate > Topaz Photo AI

  • Filter > Topaz Labs > Topaz Photo AI

I’m using the latter. Is there a difference between these?

I usually use the later, but today I confirmed both plugin has same problems.

I’d like to get some more information about the machine you are using with Topaz Photo AI while receiving these artefacts.

Please send me your system profile information so I can check if your computer hardware is up to date.

You can securely submit your files(s) to my Dropbox using the link below.

Please be sure to send me a note here to let me know you sent something.

I just sent you the DxDiag file via DropBox.
thank you

Let’s try adjusting your AI Processor to see if this resolves this problem you are having with Topaz Photo AI.

Open Topaz Photo AI and go to Preferences > General and set the AI Processor to your GPU and see if you still receive these checkerboard patterns on your image.

Hmm. The checkered pattern seems to have disappeared. But the pixel shift still occurs. This causes the edges to be emphasized abnormally black. See the GIF animation I made.

Let’s try updating you to the most recent version release to see if this resolves the issue.

Please make sure you’ve also turned off any firewall, VPN, or proxy that may be on your computer. These are known to block the installation. Also, make sure there are no settings or configurations in your OS system that could interfere.

Try using the link below to update:

Now I downloaded and installed the latest version 3.0.3, but unfortunately it did not improve the pixel shift.
There are still pixel shifts when processing on the GPU, does not occur with the CPU.

I want to see if updating your GPU driver will resolve the problem, as there is a more up-to-date driver that has been released.

Please use the following link to update your driver: NVIDIA | GeForce GTX 1080 Ti | Studio Driver Update

After the update, let me know if you are still experiencing the problem.

I tried the latest version 555.85, both GameReady and Studio driver, but unfortunately the problem did not improve at all.
Current situation;
Sharpen(Standard) + CPU = GOOD
Sharpen(Strong) + CPU = GOOD
Sharpen(Lens Blur) + CPU = GOOD
Sharpen(Motion Blur) + CPU = GOOD
Sharpen(Standard) + GPU = GOOD
Sharpen(Strong) + GPU = GOOD
Sharpen(Lens Blur) + GPU = Pixel shift
Sharpen(Motion Blur) + GPU = Pixel shift
