Do you mean like a ghost image on top of all apps? If so, it might be screen burn-in from displaying the same image for too long. You can try burn-in fixer apps or search for a burn-in video to play. These basically cycle colors through the screen to promote 'healing' and fix burn-in if the screen isn't permanently damaged.
