I am trying to export several illustrations spread on 6 Artboards of different sizes (composite of vectors and raster images) for web ads in Illustrator CC 2019 v.23.
Whenever I export my artboards (and however I do it, Export for Screens or Save for Web alike), the photo part of the illustration exports very badly:
I've tried exporting at 4x and then scaling down but even then I have a similar problem:
In the Artboard, the photo looks fine (source image is 5k x 4k pixels, and the problems happens with a 1800px version of the image too):
Setting are set as such:
At this point I'm so frustrated and angry at Illustrator's countless bugs that I'm close to just make a screenshot and call it a day. Unless if I'm missing something super obvious... Am I doing anything wrong?
