    Some people out there that have received the golden release of ML said that the issue is totally gone! I had the same issue with my 15-inch late 2011 when I was trying to open the lid and login from sleep. Something's not right about the way Lion handles switching from one graphic to another(noone's never seen this issue before Lion right?). The moment you install gfxCardStatus and you control the switching by your own, you'll see there is no problems anymore.


    If you have time until your 14 days return policy, wait and see what happens with ML. Otherwise get a replacement but bear in mind others have done the same thing and they said problem's still there.


    Good luck

    I've installed gfxCardStatus, set it to both integrated mode, and discrete mode, and it looks as though its the NVIDIA GeForce GT 650M (discrete mode) thats causing the problem.


    Switching to integrated is fine, and doesn't cause any problems from what I can see... If I leave it on discrete, lock my machine, allow the screen to power off, then unlock my machine, I can consistently create artefacting on my screen, and slow redrawing rates if I attempt to type anything, or move a window, etc; which practically renders the machine unusable in this state.


    Can anyone else recreate this issue using the same steps?

    Apple replaced my retina MBP last week, and since that time I have not had a repeat of any of the flickering/redrawing issues.

    Having the same issue on my Macbook Pro Retina 2.6 16GB   Apple really needs to get their graphics issues figured out.

  • robborrego Level 1 (0 points)

    I am having none of these issues with my machine thankfully. To the people who have this issue, are you working from a fresh install or did you use recovery assistant or Time Machine to restore a backup?

  • Jess51 Level 1 (0 points)

    I didn't migrate anything over for fear of things going wrong.  This is a fresh install.

  • Dualcyclone Level 1 (0 points)

    I used a time machine backup when setting up my machine.


    Although since I am able to reproduce this pretty consistently with the NVIDIA graphics chip, I have a feeling my issue is hardware related

  • robborrego Level 1 (0 points)

    Are you using to see when your gfx switch? It will also tell you what apps are forcing it to switch. Perhaps it happens when a specific app triggers the Nvidia hardware.

  • Dualcyclone Level 1 (0 points)

    Yep. I am predominantly using Chrome.


    That seems to be the most active app on the graphics anyway. As I understand it, they have fixed the bug they have found in their software which causes the graphics issues.

  • robborrego Level 1 (0 points)

    I would go a week or so without it. Make sure you keep it from opening at login. It could be a stray bug that they never fixed. I use Safari over chrome and I dont have any of the problems in this thread.

    For those of you that are experiencing this issue, how many of you are using 'Flurry' as your screen saver?


    And if yes, try change to 'Computer Name' as the screen saver and see whether you still have a problem...

  • Nikolaus Heger Level 1 (25 points)

    @Dualcyclone I got all these issues right away (about 1 hour from unboxing this machine).


    While I was still having the problem - totally messed up screen as many have reported - I downloaded gfxCardStatus and managed to run it (note: switching spaces makes the display appear normal for a moment, before it goes wonky again). Switched to integrated and the issue disappeared immediately.


    Hopefully it's just a driver issue.


    To me it's obvious it has to do either with automatic switching, or the NVidia drivers.

  • clintonfrombirmingham Level 7 (30,000 points)

    Have you run the latest 1.14GB software update for mid-2012 Macs? I just noted in a few threads where some problems were 'fixed' with this update...



  • Dualcyclone Level 1 (0 points)

    @Niklaus Heger - Mine appeared pretty quickly too, and seems to bare no relation to Chrome usage; it seems to only cause a problem when unlocking the machine from a sleep state. I also get a brief respite when navigating through spaces, but similarly the problem returns after a short time.


    I hope too that this is just a driver problem, but for the meanwhile, I have an appointment to meet a Genius Bar representative, who will hopefully offer an advance replacement; They will have to, since this is my business machine.

  • Nikolaus Heger Level 1 (25 points)

    @Dualcyclone: I would not bother getting this looked at right now - it's a waste of time. Yes, it's a bug, but Mountain Lion will arrive next week; it's a free upgrade for retina MacBook Pro owners. Meanwhile gfxCardStatus / setting to integrated fixes it completely. There is nothing the genius bar can do for you at this point.


    PS Donated $10 to Cody Krieger, I *love* gfxCardStatus. I don't think Apple's automated switching scheme is working very well at all, it seems to needlessly turn on dedicated graphics all the time.
