    I see screen tearing pretty often while scrolling webpages up and down, and it has been like this from day 1. But now I purchased an external monitor which is huge 23 inches compared to MAC 11, and the effect is more visible. It is driving me nuts and giving me headaches.

    I wonder if you see the same. I was reading allot about this problem, and it seems to be present on macbook pros also? can someone confirm I'm not alone?

    In other words I'm deciding weather to go through warranty repair, or if it makes no sense if all of theme exhibit same behavior.

    It is shame to see this beautiful machine, with insane price tag to be lagging when browsing web when processor is just sitting their idle at 4-12%!

    This is an example I found on wiki that more or less describes what happens when I scroll up down. Effect is not so pronounced and clears when I stop scrolling, but it is sure annoying hell out of me.

    Firefox tearing like hell, chrome less, safari exhibits jagged scrolling but less tearing of chrome and firefox.

    With synthetic benchmarks I don't see any problems with hardware. But this is not particularly revealing.

    I reckon it's something to do with the Intel HD4000. Every new Macbook I tried today did it in various extremes, the new retina MBP, the classic 13" MBP, both MBAs. And now I've got mine home on the Thunderbolt display, I've noticed it happens when both screens are running, but only in minor patches (but generally most of the time in zoomed Safari) when it's just the internal or just the external. So either, a) you and I are crazy, possible, but unlikely, or b) it's a Lion + HD4000 issue, as I've read Mountain Lion fixed up the same issues for retina people. I'm not a fake developer, so I can't say what's what.

    I see. Mine is HD3000, mba 2011. Which makes me think this is more widespread than I thought. But how come people don't notice this and complain like hell? This is a major flow either in software or hardware, any reputable manufacturer would try to fix it in time. I waited 6 month and no update addressed this issue.
