This is a 2011 Macbook 13" base model. I've owned it since August, and honestly don't even use it very often. It has sustained no damages (ie. drops, spills, or anything...).

Sometimes, quite frequently, my Air's screen will look like this in the log-in screen after waking it from full sleep. It looks like the image is scrambled. Once I log in, the screen goes back to normal.

Has anyone else experienced this? Is this a sign of a failing screen to come?

As I always advice, please perform a hardware test to make sure nothing is wrong and to prevent any problems from escalating.

Apple Hardware Test

If there's something wrong with the display, which I doubt, it will most likely tell you. I have a feeling it could be the graphics card, though, because that's what my 2008 MacBook Pro displayed when the graphics card was failing. If I had done a hardware test earlier, I'd have been able to replace it for free under the one-year warranty. Luckily it was a universal problem with that specific GeFoce card, though, which gave me a 4-year extended warranty.

Good luck.

My 2011 MacBook Pro does something similar from time-to-time, but only since upgrading to Lion (and only when waking from "safe sleep").

Personally, I think this is a bug in Lion - but I'm curious to see if it goes away after you close the lid and reopen?
