Makes mutter (which propagates to gnome-shell) request a low priority real-time
scheduling which is only available on the wayland session.
To enable this experimental feature it requires a restart of the compositor.
Note that enabling this option only enables the <emphasis>capability</emphasis>
for realtime-scheduling to be used. It doesn't automatically set the gsetting
so that mutter actually uses realtime-scheduling. This would require adding <literal>
rt-scheduler</literal> to <literal>/org/gnome/mutter/experimental-features</literal>
with dconf-editor. You cannot use extraGSettingsOverrides because that will only
change the default value of the setting.
Please be aware of these known issues with the feature in nixos:
