I have found a way to do this.
Create (if necessary) a ~/.profile file and add the following:
WAY=$(ps -aux | head -n -1 | grep "/usr/bin/gnome-shell --wayland")
if [ -z "$WAY" ]; then
echo X11
else
export GDK_BACKEND=wayland
export CLUTTER_BACKEND=wayland
fi
Logout and then login in your favorite session (either X or Wayland). By using looking glass you can check if your application is actually running on Wayland. See this.
