If we have repeats on for a full-sized image, then if the background is displayed scaled (for example, in a desktop preview mode) then we can get artifacts along the edge of the background where the repeat of the opposite edge is blended in by bilinear scaling. So turn off repeats when the screen and background image sizes match. https://bugzilla.gnome.org/show_bug.cgi?id=634833
