    Flickering black boxes when editing on macbook pro

      Hi!

       

      After I updated my macbook pro to the newest Yosemite software (which I really regret because my mac is now running soooo slow ), I have experienced that

      small black boxes flicker whenever I am editing pictures/using brush tools in Photoshop.

      I have heard that the same problem happen some time ago with the macbook air but now it is happening to me! I have tried to turn down the Graphic Processor from "Advanced" to "normal" but did not help.
      What can I do? I am going crazy seen those boxes flicker every 5 seconds!
