[starting in lightroom, then Edit in Topaz Photo AI, i noticed lately that artifacts are shown in the picture, as if you are using a laso tool and forgot to exit it…
the thing is that the final image is keeping the artifacts.
Note: ive been using Photo AI for around 1 year, never had this before
i am keeping the system always updated
Same here. Seeing strong aliasing and moiré patterns in the preview. I expect it has to do with the down-sampling filter used to scale high resolution images to a smaller resolution viewport.
It looks like a computationally cheap interpolative filter is used, e.g. nearest-neighbour.
Even a (still cheap) bilinear filter would look better. Using a windowed sinc (Lanczos) filter would be best for shrinking/zooming out.
Scaling is already at 100%, so that’s not it. It is something in the Topaz UI/preview rendering, because the saved output when viewed in an image viewer (with proper downsampling) does not show the issue.
