Currently my MBP (15" Retina bought in June 2012) getting this 'WHITE SCREEN' after idling for about 10mins or when re-open the lid. There is nothing on the screen except just 'WHITE' and NOT even the mouse pointer or cursor. 
NO respond on the keyboard so have to press & hold the switch-ON button to restart. Then only back to normal.......but after idling again then same WHITE-SCREEN.
Does anyone experience this problem ? Appreciate your feedback....thanks
