A bit more information potentially useful for debugging: * Once the bug occurs once, it keeps recurring every time the screen locks at least until gnome-shell is restarted. (It's possible it only occurs on idle; I forgot to test manual lock before restarting gnome- shell and losing the buggy behavior.)
* I, too, get the problem where mousing over some dock icons (particularly ones that are not pinned) causes the icon spacing to expand, leading to a bit of sideways jitter. This does not happen every time. Strangely, when it does happen, I *don't* get the problem where my non-GNOME tray icons (Dropbox, Skype, etc.) disappear after unlocking. * With more careful experimentation, I was able to isolate some journalctl errors from the time of locking and the time of unlocking. I've attached the journalctl output. ** Attachment added: "journalctl-before-after.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1769383/+attachment/5228577/+files/journalctl-before-after.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
