  * gdk/gdkscreen.[hc] (gdk_screen_x11_get_monitor_at_window):
    remove virtualization and made it cross platform. fix #79961
  * gdk/x11/gdkdisplay-x11.c (check_solaris_xinerama):
    fixed initialization bugs.
  * gdk/x11/gdkscreen-x11.[hc] (gdk_screen_get_monitor_geometry):
  * tests/testxinerama.c:
  * gtk/gtkwindow.c (gtk_window_compute_configure_request):
  * gtk/gtkmenu.c (gtk_menu_position):
    take a GdkRectangle argument instead of returning
    a GdkRectangle * and propagated the changes. fix #79974
