macbook pro core i7 high res anti-glare screen garbled graphics

My two month old macbook pro consistently (once every day or two) produces a garbled up screen after using it for a few hours. The only way to resolve this is to restart the computer. I've talked with apple support and have gone into the store for help and so far everyone is clueless and offer no real advice. I can't take a screenshot on the machine once this occurs, the picture just comes up blank, but I did take pictures with my cellphone.

Has anyone else had a similar issue and is this most likely a graphics hardware error?

Welcome to Apple Discussions!

It looks very much like a graphics chip issue to me. Next time it happens, try running the extended version of the Apple Hardware Test and see if you can get an error code. If you do, it will point to a hardware problem. If you get the same image on an external display, it would indicate a graphics chip problem.

Did the Apple Store see anything in person or just your picture? Did they run any kind of hardware test?

Can you correlate this with anything specific like temperature or graphics intensive software? If you can make it occur in front of a genius, it would help. They have to see it or see an error code before they can really do anything.

Good luck!

The last time I talked with apple support we ran an extended hardware test and it reported no problems. When I went to the apple store the machine at the time was not exhibiting the graphics issue and I had not taken shots with my camera at that time. They ran a series of intensive graphics tests to see if anything would break. After about 5 minutes of my machine rendering everything perfectly they sort of said there wasn't much else they could do and next time it happened to try support again.

This appears to not be related to anything, there have been times where I've been doing low intensity stuff like browse the web (no flash) and it starts to happen. Other times I've been in the middle of programming running a couple of servers and whatnot and it happens. I believe twice now it has happened after waking up from sleep.

I've also switched it over to the more powerful graphics card expecting to see issues right away, but it didn't happen.

If you can run with the more powerful discrete GPU and have no trouble for long enough to make you confident that it isn't going to happen, and then you switch to the integrated GPU and the problems reappear frequently, that points to an intermittent fault in the integrated GPU. Run the extended version of the Apple Hardware Test that you'll find on one of the DVDs shipped with the computer. If no errors are reported the first time, run it each night for several nights while you sleep. Make careful note of any error message it reports, and take that to the Apple Store or call AppleCare with that information.

If the problem occurs with both GPUS, the problem is likelier to be in the video cable or the LCD panel, neither of which is or can be tested by Apple Hardware Test.

I have the i7 with anti-glare...I get similar results when I have multiple safari windows open that use flash. If I go to preferences and turn off automatic graphic switching it typically solves the problem. Seems like a software issue, pretty annoying. I posted previously and included a screenshot:

I switched to the discreet graphics card and have yet to run into this issue. Really ***** because I don't do anything graphic intensive and would much rather have longer battery life.

Also my error doesn't appear to be specific to safari. It certainly does happen in safari, but its also happened to textmate more than once and restarting those applications does not get rid of it. The only way to "fix" the problem is do an entire restart of the machine.

As the original poster stated, the Apple folks don't know what the problem is, so what will Apple do about it? It seems like a graphic switching software problem, no? I am in the same boat, but don't really want to send back my machine just to get another machine with the same problem if it's software related. There have been reports of this problem in the apple forums and the macrumors.com forums.

Have you run the extended Apple Hardware Test several times, as I suggested above? Have you photographed the display anomalies when they appeared, and shown the photos to an Apple technician or Genius as proof that there is a problem?

If you're firmly convinced that there's a software and not a hardware problem, erase your hard drive and reinstall your OS.

Quantify several...

I have photos (see below), but I personally have not been to the genius bar. However it sounds like the original poster has, but without resolution.

Erasing the hard drive and reinstalling will not help if it's a software problem related to safari, flash, and graphic switching (ie. snow leopard). Safari, flash, and obviously snow leopard are by default installed on the computer. Therefore, the problem will occur again.

My point is that I do not want to go through the hassle of getting my computer's hardware "repaired", just for the problem to re-occur due to Apple software problems.

I will run the extended tests several times when I get a chance, hopefully later on tonight. I'll report back what I find out.

I have noticed in the past 2 days since switching over to the discreet graphics card that safari has crashed a number of times. Before this safari rarely if ever crashed, now its crashing at least 2 -3 times daily.

Sep 22, 2010 3:49 PM in response to drm31078

Drm31078, it sounds like you've made up your mind what the problem is and decided to wait for it to fix itself. In light of ryanfitz's experience, which now indicates that the problem occurs when using each of his two GPUs, I question your conclusions that there's a graphics switching problem and that Apple's basic software is at fault, simply because there are thousands of other users with the same machine and the same Apple software who aren't seeing the same behavior. Therefore, I recommend that you run the extended Apple Hardware test repeatedly in hopes that it will eventually detect an intermittent hardware fault, bearing in mind that if there's a fault in the video cable or the LCD panel, AHT can't and won't detect it. And I recommend showing your pictures to a Genius or an authorized service technician for evaluation. A single Apple employee's failure to detect a hardware problem is not conclusive evidence that none exists, and I don't think there's any good reason to dismiss that possibility out of hand on the basis of what you've seen and heard so far.

I just spoke with apple support, showed them this thread, and the pictures of what is occurring. It is now being escalated to the engineering team. Anyone else running into this issue I think should call up support as apple was not familiar with this issue at all.

I also started looking at my crashed safari logs and noticed its crashing with some open-gl error so that at least (and hopefully) points to a software issue that they could fix.
