I have noticed on my HD mobility 4200 Series card and with the open sourced drivers, most of the screen flicker in Gnome Shell happens when there is a windows shown and you mouse to the bottom right hand corner to see notifications. The sides of whatever window is open will flicker black when the shadow gradient appears at the bottom of the screen
