I very recently purchased an i7 2.6Ghz Hi-Res 15" MacBook Pro and notice a very strange behavior. If I leave the laptop so it goes into sleep mode there are problems when trying to waken it. Usually I press the space bar a couple of times as my method of waking it up and then the display changes but weirdly.


From the bottom left-hand of the password box up and across the screen it, on most occasions, displays the usual background. However the rest of the display is blank, a white screen. As I move the mouse the around this area the screen pixelates.


I have tried changing all energy saver settings without any luck, so it this a known problem before I phone Apple technical support?



MacBook Pro (15-inch, Mid 2012), OS X Mountain Lion (10.8.2), Hi-Res screen
