The compression affected the wallpaper quality quite a lot, especially at lower resolutions. There are some artifacts (unnaturally bright pixels) F7980960: 2020-01-27_21-05.png <https://phabricator.kde.org/F7980960> If saving space is very important, JPEG format may be the best option. The loss of quality for this kind of image (lots of noise) is minimal.
