I've worked with 2D graphics quite a bit and I've often used anisotropic smoothing[1]. GAN images have similar artifacts (probably worth thinking about, btw), which are trivial to spot if you know what you're looking for. They look like waves on water[2]. One could mask these artifacts by blurring, adding noise or downscaling further.
