    RiP Steve.

    I have had problems with the graphics in OSX all the time since I installed Lion on my new iMac 27".

    That´ll say they are not present all the time, but I get little errors on the filemenu, dock, around the edges when I move a window, etc.

    Check out the screenshots: and

    These small little errors persist all the time when they have first occurred. Only restarting removes them (can´t verify that logging off and on removes them, but I forcefully removed all the processes via activity monitor earlier today without any luck).

    Any tips on fixing this?

    I am on a clean install of Lion via USB-stick and have downloaded all the latest updates. New iMac 27" as of july 2011. 3.1 GHz Core i5 and 8GB RAM.

    I think your graphics card is shot.

    Have considered that myself... Will let the store which I bought it from take a look at it, if it can´t be fixed with drivers or patches to Lion.

    I'm not saying that you shouldn't get it looked at, but i will say that my macbook pro suffered a similar problem after clean installing to Lion. After going back to Snow Leopard, I haven't had a single graphical issue. Try dual booting with snow leopard and see if you can replicate the problem there.

    Hi GuerillaTech, thanks for your reply :)

    My suspicions are on the same here.... I didnt either have this problem with Snow Leopard, which was installed earlier on this Mac, and Lion have been really buggy (almost tempting to call it Apple´s Windows Vista...!) with lots of other minor problems.

    Must be either on or the other...

    No problem. :)
    At first, Lion was perfectly fine.
    Eventually all the problems started to show, such as kernel panics and graphics issues.
    I switched back to SL after a little over a month (10.7.1 changed nothing).
    I am anxiously waiting for 10.7.2 to give Lion another chance though.

    I have had kernel panics also... Maybe it´s some of the installed apps that makes the graphic mode in Lion to act up ??

    Any way to check whick apps is safe or not ?
