Hai. Everytime I boot my MBA 11" (early 2014), I get this scrambled grey screen for about 2 seconds. It boots up normally after that and no other problem persists. I bought this laptop about a month ago and it has been under heavy use ever since. I'm on Mavericks 10.9.5 (downgraded from Yosemite some time ago) Is my GPU failing or something? EDIT: Reinstalling the OS from the Recovery partition fixed it.
