Older Gnome Wayland application crash on Ubuntu 22.04.4 LTS

[Gonzalo Garramuno]

I build my Wayland C++ viewer (mrv2) on Rocky Linux 8.9 to make it compatible with the largest set of distros (and to be in sync with the VFX platform recommendations).
When the binary is run under Ubuntu 22.04.4 LTS Wayland, it crashes due to a Gnome incompatibility setting:

(mrv2:540344): GLib-GIO-ERROR **: 20:47:45.978: Settings schema 'org.gnome.settings-daemon.plugins.xsettings' does not contain a key named 'antialiasing'
Trace/breakpoint trap (core dumped)

The current work-around is to do the following on Ubuntu 22.04.4 LTS:

sudo cp /usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.xsettings.gschema.xml /usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.xsettings.gschema.xml.bad

sudo nano /usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.xsettings.gschema.xml
    (remove lines 19 and 20)
        < </schema>
        < <schema id="org.gnome.settings-daemon.plugins.xsettings.deprecated">

sudo glib-compile-schemas /usr/share/glib-2.0/schemas

It would be ideal if Gnome or Gnome Settings would keep backwards compatibility. Printing a warning and not dump core, would be okay too.
