I've got 5-6 desktops going in mission control and I have a random wallpapers on each that change every 30 minutes. I've become very annoyed with the fact that OS X doesn't change the desktop on a space I'm not using until I switch to that space. I'm getting tired of seeing fading wallpapers every time I switch to a desktop.
The only thing I've come up with is running killall Dock but that's pretty brutal and I don't want to run it all the time.
Is there a way to get OS X to refresh all the desktops at once? Are there any defaults write tricks for this in Lion or Mountain Lion?
