MacBook Pro Retina 15 - Strange display behaviour when waking from sleep

HI,

i have had my MBPRetina for about a month now and last week it started to behave very strangley when waking from sleep mode (induced by closing the lid). When I open the lid the unlock screen appears but then i get a strange kaleidoscope effect where it almost looks as though the screen is cracked! This happens either at the password prompt or on the main screen after the password has been entered. Sometimes it freezes and i have to power off and on again to get the system back. it doesnt happen everytime either.


I am running ML 10.8.2.


Any help would be appreciated as it is getting more frequent.


thanks.


Matt.

MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)
