Hi, From time to time I have some weird issues where, mostly in Safari, the design of a website would look pretty weird until I either reload the page or select all (CMD+A) then click away. It definitely isn't a problem while loading the page, it happens on many website and whether I'm on Wifi or using a 3G hotspot. It's hard to explain but you can see a screenshot below where you see a lof of white where there is actually content that should be visible. Any idea how to fix this? I doubt it's a hardware issue because I don't have any issue while playing a game or watching a video for example. Also, I'm pretty sure I never have the issue when using an external monitor. This plus a weird sound crackling on iTunes from time to time... it's a bit too much for a pricey machine like this... Thanks!
