Image Flicker While Changing Apps

view story

http://androidforums.com – recently one of my backgrounds i use to have been poping up quickly when i change between apps. i deleted the picture long ago and its still doing it. i thought it was a go launcher problem so i tryed using different home launchers but still happens. its kinda annoying. i havent try to do a factory reset because im not going through that .. but has this happen to any 1?
