[Spice-devel] [PATCH spice-gtk] spice-widget: Do not invalidate cursor when display is not ready

[Pavel Grunt]

spice_display_get_scaling() gives wrong x, y coordinates and scaling
when the display is not ready. The wrong values cause runtime
warnings when disabling a virt-viewer's window:
Gtk-CRITICAL **: gtk_widget_queue_draw_area: assertion 'width >= 0' failed
