Loaded Catorise to organize apps. Drag screen so that the live
wallpaper of the city (doen't matter if it is day or night scene) appears. Wait a few seconds. Now tap on upper lefthand corner of
screen to go to the Catorise screen. A horizontal narrow hazy region is seen between the middle three directory icons. If I now go back to the original screen (that has the splashing water) and tap to get to the Catorise screen it appears normal with no hazy region.

I uninstalled Live wallpaper and reinstalled it today and it still happens. Hope this helps sort it out.
