Is the greeter *always* mapped before the "saver" is run?
In case just delay it - run the "saver", ensure an XSync, pray the "saver" has taken the desired screendump to operate on - then map the greeter below the "saver".

Humm? On a map/exposure event the window should repost it's content - do you have an example xss hack?
Alternatively one could just stack the "saver" below the greeter (and restack later on), but w/o compositor that does hardly differ from the unmap/map case.
