Prior to updating to Mavericks I used LotsaWater screensaver. It would display my desktop while the screensaver did its thing. Now it shows a blank white screen when it kicks over to the screensaver mode.
Under System Prefs>Desktop & Screen saver, the preview window shows how it's supposed to look and if you tap on preview it works right.
Is it that the maker of this screensaver hasn't made it compatible with Mavericks? Or am I missing something?
