OK, I just experienced the issue again after resuming from suspend with the new package installed. (Not sure whether the package version number was updated for the candidate, but I'm using the one with SHA1 e51a7f3a77c2643714b9ca68b6707584c82784ce.)
I've attached the journalctl output. There's a very faint chance I didn't restart yesterday after reinstalling this package, but I've certainly restarted gnome-shell quite a few times, so I'm fairly certain the problem is recurring even with the fix. Devs: please let me know if there's something else I can do to help test or resolve this problem. ** Attachment added: "journalctl.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1769383/+attachment/5228409/+files/journalctl.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769383 Title: Ubuntu dock/launcher is shown on the lock screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1769383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
