Default Different Wallpaper for Home screen and Lock screen ?

Has anyone been able to get different wallpapers for the Home screen and Lock screen to work without the colored block on the lock screen ? I tried several apps and xpose modules but nothing works. Only way i can get different image is by enabling custom lock screen in settings, but then i end up with the colored block, if i uncheck it , the wallpaper stays the same on both screens I read that it is a CM thing ? Can you suggest an xpose module that works ? I tried Gravity box, Xblast, and a couple more that say they do but don't.

Don't want that -_-
