Thanks for the bug report. It appears at least half the problem was using an old unsupported graphics driver, which makes this a duplicate of bug 1867668. To be sure you have removed that so we can focus on the remaining issues more clearly, please now open a new bug by running: ubuntu-bug xorg and then tell us the new bug ID. ** This bug has been marked a duplicate of bug 1867668 Visual artifacts in Gnome Shell when using the 'intel' Xorg driver on 8th/9th gen Intel hardware -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875645 Title: Graphics corruption on shell on login screen and session screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1875645/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
