The background rendering issue seems a gnome-desktop3 bug, attaching a small testcase
to compile: $ gcc -o background background.c `pkg-config --cflags --libs glib-2.0 gdk-3.0 gdk-x11-3.0 gio-2.0 gnome-desktop-3.0`
to try in a normal/unity7 session - close nautilus (nautilus -q) so nothing renders the background - run GDK_SCALE=2 ./background - look at the result
