Web Images and App Store Icons are distorted in MacBook Retina Display
Recently, most of the icons on Mac App Store are distorted. I also noticed this on web images when browsing using Safari or Google Chrome. By the word "distorted", I mean that the image was not properly loaded, it contains pink lines and multiple blue and pink dots. I even experienced this on Apple website. When I click on "Shop", the images for Macs, iPod, iPhone, etc. are distorted or you can see some image ghosting. I haven't experienced this issue on other non-web applications like Office, Finder, etc.
Do you think it is a problem with my machine, or my internet connection? My internet connection seems fine when I use other laptop or computer. I even tried browsing the web around 3 AM in the morning when the connections is fast, but the issue is persistent for web browsers (Safari and Chrome) and for App Store as well.
I am using 13" rMBP, by the way.
MacBook Pro with Retina display, OS X Mountain Lion (10.8.1)
