[Daniel van Vugt (vanvugt)]

If the autohide setting is causing the gnome-control-center window to move or resize (and then "glitch") then this could be bug 1947149.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Akbarkhon Variskhanov (kbar)]

There are two glitches here:
1. Selecting the Appearance tab for the first time causes the Dock to disappear briefly.
2. Toggling the "Auto-hide the Dock" setting causes the Dock (plus the Settings icon) and the Application menu to flash and re-render.

Screencasts are attached below. Pay attention to the Dock (plus the Settings icon) and the Application menu.
