Lock screen going blank

A

AC Question

I am not sure if this is because of the new marshmallow update, but every once in a while when i press the power button to unlock my S7, the lock screen is not black because i can still see my wallpaper but there is no camera, phone or hour icon and the finger scanner still active. Does somebody know why? it is a bug with a solution? or it is something that i have to learn to live with ? lol.
Thanks in advance,
