What happens if you replace:

  scale = gtk_widget_get_scale_factor (FRAME_GTK_WIDGET (f));
  cairo_surface_set_device_scale (surface, scale, scale);

With:

  cairo_surface_set_device_scale (surface, 1, 1);

But aside from that stab in the dark, I'm really clueless as to what
might be happening.  Thanks.
