There's a discrepancy between the screenshot in comment #1 and that in comment #3. The screenshot in comment #1 shows extensions clearly running, and the screenshot in comment #3 suggests there are none.
After you have disabled all extensions, please: 1. Log out and in again. 2. Tell us if the bug still happens. 3. Provide a new screenshot of the whole desktop. 4. Run this command: gsettings list-recursively org.gnome.shell > settings.txt and attach the resulting text file here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1882353 Title: Ubuntu Dock and Top bar accessible from lockscreen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1882353/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
