I have a file that I successfully exported to screens. A month (and an illustrator update) later, I needed to make an edit and when i did so, the embedded yellow graphic now appears pixelated with dark pixels around it. I am current on Adobe CC 2021, on a 27inch iMac running OS Catalina 10.15.7.
Weird. Yes, GPU acceleration was on, but I also selected "View with GPU" and that seemed to fix the issue? What the heck? I hate that I will always have to double check the 20 images i export multiple times during review to see if the embedded images are rendering properly.
