problem when opening the s view cover s5

[fdk2008]

there is a black shadow that comes on the top of the screen,This happens only when i open the s view cover when the phone is awake(s cover closed),and selected to unlock when opened,this started happening recently,and also when i am using a downloaded wallpaper that shadow comes and stays there permanent but when using a stock wallpaper it just flashes when i open the cover
