[Bug 1870725] Re: artifacts appearing on gnome shell

[Chris Guiver]

Thank you for taking the time to report this issue and helping to make
Ubuntu better.

If you change wallpapers, does the issue still occur?  Does it occur if
you have windows fullscreen (eg. if firefox is your open window and
maximized so it covers your wallpaper, do you see the artifacts?) or are
they visible only on your wallpaper?
