OK, I searched and found this issue on AppleDefects but nothing on MacRumors. So I decided to install Windows because I needed to use a piece of software and I didn't feel like using the software on our 9 year old HP desktop. I've installed Windows/BootCamp before but that was back in the Tiger days. I had no issues and removed Windows promptly after I was done with it. Anyway, I used "Startup Disk" in System Preferences to start up in Windows, and my screen looked blue/greenish/fuzzy. I restarted the computer (back into Windows) and everything looked fine. Fluke I thought. Windows doesn't belong on a Mac anyway right? Did what I had to do, went back to OS X, no issues. Then I went back to Windows again, there goes that fuzzy issue. But guess what? Now it won't go away. And the issue appears in OS X now!!! Here's what it looks like: But here's the kicker... it doesn't happen on an external monitor... What do I do here?
