Q: Macbook pro 15. Intel HD Graphics 3000/ AMD Radeon HD 6490M. Screen seems 'solarized'/pixellated at startup. disappears after 30 minutes. Any idea of cause and cure?

New Machine in Mar 2011. OS version 10.6.8

All software updates installed via Automatic update.

Screen has a 'solarized' look on start up, which disappears after about 30 mins, suggesting a 'warm up' issue?

Am aware of Nvidia issues with Macbook pro but this machine has the following graphics/display on logic board.

 

Does anyone have a view on this matter and a way of resolving it? Still under extended warranty.
