Right now we take a still frame of the desktop before showing the start up animation. This gives us an animation over what was there before startup. That's not actually desirable when restarting the shell. We don't want to animate over undecorated windows, we really want to animate over the noise texture. This commit drops the still frames in favor of the noise texture. https://bugzilla.gnome.org/show_bug.cgi?id=694326
