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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870725 Title: artifacts appearing on gnome shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-meta/+bug/1870725/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
