The redesigned MacBook Air is only two weeks old, and reports of display issues have begun to crop up.

Cult of Mac reported earlier this week that it noticed flickering horizontal lines sometimes appearing on the display of its 13-inch model. A quick check of Apple support forums reveals a couple dozen reports of similar issues.

Though Apple has yet to publicly acknowledge the problem, a leaked internal memo shows that the company's support staff is indeed aware of it. Boy Genius Report received the memo from an unnamed source, and published it today. 

Sources tell BGR:

(T)hat the manufacturer is investigating several of them internally. Included among the issues is a bug where the display flickers or shows horizontal lines of varying colors when a computer wakes from sleep or after hot-plugging a display. Another bug causes the screen to fade from light to dark repeatedly after waking from sleep. Apple's internal support system includes suggestions for interim fixes in each of these cases, but no permanent fixes are available at this time.

We've reached out to Apple for comment on the memo and the issue with displays to see if it will confirm either. We haven't heard back but will update the story if we do.

If your Macbook displays flickering lines all the time not just when it wakes up from sleep, then your LCD is probably at fault. Dr. Laptop can do diagnostic on your LCD and see if they can fix the issue with the same LCD but if not we can always replace the LCD with a brand new screen. We will keep you updated if Apple offers any kind of warranty replacement for this particular issue besides rolling out software update.
