gnome shell dock goes blank

Sometimes the Gnome Shell dock (application launcher strip) goes blank.

To get it back without logging out and back in:

Press Alt + F2

Type r

Press Enter

This will restart GNOME Shell while keeping your applications running.

To do this in a shell script:

#!/bin/bash

dbus-send --type=method_call --dest=org.gnome.Shell /org/gnome/Shell org.gnome.Shell.Eval string:'global.reexec_self()'
