I use Polonium, so windows almost never overlap and they're always in front of the wallpaper. Blurring the wallpaper only once, keeping it in memory and drawing it behind the windows would result in a reduction of the GPU load, which would also result in longer battery life on my laptop.

Of course this would be an optional feature.
