I've attached the requested output. I have done additional testing today on my Dell XPS laptop running Ubuntu 19.04, my personal desktop running 18.04 and my work PC running 18.04.
* I removed all extensions, uninstalled packages for those that had them or deleted via the gnome extension website. * Rebooted * Re-enabled magnifier and switched between 'Full Screen' and 'Left' Screen parts. I see the issue on all three machines though on 19.04 the effect is slightly different. Opening the activities overlay causes the issue to fanish until it is closed again. ** Attachment added: "lspci -k output" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1831140/+attachment/5268095/+files/pc-lspci.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1831140 Title: GNOME Magnifier Flickering when using none-full screen modes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1831140/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
