    It's not an Ivy Bridge issue, same thing happens on Sandy Bridge.  I'm a late-2011 MBP and it happens here after 2-3 days of browsing.  Restarting the browser fixes the issue, which is only triggered by some sites (fortunately not sites that I visit often).  The only thing I can tell is that once it starts happening it happens on all sites and the browser goes on a downward spiral into LSD reality.  The actions that used to cause issues to me was replying to comments on Slashdot.

     

    EDIT: Amusingly enough, one of the aforementioned rendering issues caused me to post a lot of nonsense before this edit.

    I have an "old" MBP with an old Core2Duo and nVidia 9600M and I had the same problem before fixing it.

    I think I found a reliable way to reproduce the problem.  Maybe someone else can try it out and report on the results.

     

    Do a Safari Reset and reopen the browser to ensure that all rendering issues are gone, then go to the Apple Store (http://store.apple.com/) and select to buy something (I used a 12-core Mac Pro).  In the configuration page, there should be a box on the right with Apple's phone number and the price of the purchase which scrolls along with the page -- this box will cause the issue.  In order to trigger the problem, scroll all the way down and start resizing the browser window vertically until that box disappears and then slowly resize it back to the exact point when it reappears.  Once the box reappears, try scrolling down as quickly as possible to trigger the rubberband effect, which will also cause the boxx to flicker a lot.  At this point the browser is corrupted and the rendering issues will slowly start to appear on all sites; the longer it remains open, the worse the rendering issues will be.

    It doens't work for me.

    "doesn't work" is not proper reporting.  Please, try again, next time with more details of what you did and what "doesn't work".

    I followed your instructions in order to reproduce the rendering issues. And I couldn't reproduce the problem using your instructions.

  • 171. Re: safari rendering issues

    I recommend reading my instructions carefully, namely the part where I mentioned that the rendering issues will start to SLOWLY appear on all websites.  If you missed, I have legitimate reason to question whatever else you missed.

    Also got this problem when typing in message boards. Bloody annoying

    Thanks for bringing the issue up.

    I also have similar problems and at first it looked like hardware problem. I I still think that it may be a hardware problem, especially after one of the posts I saw here, where it was mentioned that only users with dual gpu experience this problem.

     

    Here are the images of example that make my experience in borwsing terrible:

    Have you set a Firmware Password on your machine? If so, reboot while holding Command-R and then go to the top (menu bar) and select Utilities > Firmware Password Utility and click Turn Off Firmware Password.

     

    After you do this, reboot. Thennnnnnn, reboot agat holding the "d" key and the ATH should come up.

     

    Hope that helps.

    It may not be only related to the browser's video rendering!!

     

    Please look at my examples of the Horizontal lines that I have:

    http://postimage.org/image/lihagn8px/

    Looks like the ones that the one posted by Mike in Tampa Bay

    Now the most interesting thing.

    When I sterted having these horizontal lines I suspected that it may be a GPU hardware problem.

    I went to my local Apple dealer - Saturn (Berlin, German) and the Apple Customer Service guy pointed me at

    this

    https://discussions.apple.com/thread/4148522?start=90&tstart=0

    topic and informed me that it is definitely a browser's rendering issue. And I thought that it was ever since.

    Three days later after I watched a movie and played a video game I started my Logic 9 and I noticed this:

    http://postimage.org/image/xml153noj/

     

    Do you see these 2 black lines? It means that the problem is not only in video rendering of the browser's ouput.

     

    For me it still seems like it is a hardware problem.

    I've been using computers for last 20 years and I have never seen that any software could cause such video artefacts. I hope that I am wrong, becaus if it is a harware problem it will be very hard to make Apple to exchange the GPU or the entire logic board until it wil die completely. And the thing that it may happen after 2-4 years of the use of the computer, when it will be out of warranty and apple care 3years limit.

    Similar thing happened to some of Apple Macbooks users with ATI Radeon X1600 mobile and the GPUs on 2006 and 2007 Macbook Pros.

    I did it 1 day before. All AHT phases passed 100%. I don't think AHT can detect all the problems that GPU can have.

    Please don't contaminate the discussion with anecdotal evidence.  You may indeed have a hardware issue, though that does not mean this is a hardware issue.  Like most of the people here, I only started to have this issue since Mountain Lion (or Safari 6), Safari is the only application that manifests these issues on my system, and the situation has actually improved for me as Safari received updates (Safari 6 was borderline unusable when it was released, now it takes a couple of days before the rendering issues appear).

    Yeah the above certainly is nothing like the problem I'm having, my problem is soley with text not appearing and only to my knowledge with Safari
