Wix images are blurry now?

It seems to have happened this week

I’m not sure what’s happened but all the images on my site are grainy and blurry from anything that’s been cut and pasted back onto the web page.

I feel like I’ve changed a setting somewhere of something that I’m not certain of.

I can make an image on a graphic editor and upload it to weebly and it’s fine but on wix it’s grainy with dark edges and a blur. Can anyone guess what the issue is?

I’m clearly not having the issue in weebly and I’d rather not migrate my site elsewhere but the image difference at the moment has rendered wix completely unusable to me. It’s even worse on colored backgrounds where the images look 1998 quality.
