I too am one of many experiencing display flickering with my 15" SR MBP. But there's one thing I noticed - I don't see any flickering while using Vista via Boot Camp. For comparison, check out the following image: http://www.avms12.dsl.pipex.com/MBP17HiResLogicPro.png (Originally posted in http://forums.macrumors.com/showthread.php?t=323847) While the image flickers terribly in OSX, it looks just fine in Vista, no matter what brightness setting I use. This leads me to believe that the problem we're experiencing is software related, not hardware. Can others who are experiencing flickering verify this as well?
