When there was no root background pixmap, we were using a 1x1 repeating texture as a simple way of drawing a solid color without adding a second code path. However, when that 1x1 texture was combined into a larger "atlas texture", hardware repeat couldn't be used, so a small inefficiency from this approach became an enormous inefficiency as clutter drew every pixel of the background as a separate rectangle. https://bugzilla.gnome.org/show_bug.cgi?id=652507
