Genertive fill problems with pattern of intersecting lines

[Isaias34062145kad5]

I started using generative fill recently, and I'm having problems with the generated images, they all have a pattern of intersecting lines, no matter the size of the portion of the image, even if it's a small correction. What will be the cause of this?

Was the Selection less than 1024px x 1024px?

both, in small selections in the image, or even larger selections

Could you please post screenshots taken at View > 100% with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible for a case in which the Selection is smaller than 1024px squared? 

Ultimately Generative Fill may just not live up to your expectations/needs.
