My lovely new toy is acting up and before having to try (Applecare's) last resort of wiping everything I've done to set up this machine and start again I'd be hugely grateful if anyone has any suggestions. Basically my screen gets screwed up whenever anything changes on screen e.g. typing, movie, moving window, scrolling etc. Then it looks like this: http://www.malw.co.uk/photos/screencap2.jpg I've done an archive reinstall, reset the pram, there are no startup items in that folder and the problem suddenly came on yesterday afternoon. The only thing I did this week in terms of new software was an update of the flash player (Apple don't seem to think this could have affected things but I unstalled anyway to no avail). Anyone seen anything like this? Given that the display is fine in safe mode I think that the problem is software based but I'm willing to take any advice. On that note, this is a custom build (2.8ghz) - can I still take it into the store for help? I'm a procare customer so I hope so.
