"Light" screenshots need to be updated (glitched logo was used)
wallpapers@a656ccfe worked around an issue during wallpaper generation that caused ugly and incorrect images to be created. See the GitLab comments on that commit for an annotated screenshot example. At first glance, the black-and-white polyguin logo looks pretty slick, but it is incorrect and has artifacts.
The "light" screenshots were captured before that was fixed, which was before the wallpapers-1.1
release. The wallpapers, when installed, are correct and do not need to be updated.
