I can confirm this - except the freezing/non-responding on a fresh Ubuntu Installation. I installed with 18.04 and upgraded to 18.10 afterwards. The default dock (no dock extension in use) is visible and fully functional at the lock-screen. The problem occurs not always, but - estimated - at over 50% of all lock-screens.
Full functional dock, e.g.: - Execution of the Favorites/applications is possible - Pre-view of application windows is possible -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1799430 Title: Icon dock visible on lock screen Status in mutter package in Ubuntu: New Bug description: When locking the machine with alt-L the icon dock is still visible.
