anyone know how to turn off background transitions?

When the wallpaper clock screenlet updates, the transition effect creates this disgusting fade to the default color. Is there any way to disable transitions? I've dissected gconf-editor to no avail. There must be a way to turn off the transition/fade effect. Anyone know how?
