>>1856596I'm using Windows 10 (botnet, I know, but this is my new laptop, what can ya do), and what I've noticed is that when I use JPGs, it compresses the image (I'm assuming because JPGs are common for pictures) and the artifacts are horrendous, but when I use PNGs, there is little to no compression, at least that I can see. I checked the actual files in C:\Users\Your User Name\AppData\Roaming\Microsoft\Windows\Themes and it looks like it still converts them to JPGs, but it doesn't compress them (or at least as much. Pic related is the same picture in PNG and JPG formats comparing Windows' compression.
