Mutter Updated for GNOME 3.20 to Fix the X11/Wayland Copy and Paste Interaction

The GNOME developers are always hard at work patching bugs in the popular desktop environment used by default in many GNU/Linux operating systems, and today they’ve updated the GNOME Shell and Mutter components. By the looks of it, the GNOME Shell user interface is now at version 3.20.3, fixing a memory leak that was also patched in the GNOME Shell 3.21.3 development release, and adding better handling of VPN (Virtual Private Network) service aliases in networkAgent.
