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?

{quote:title=jtonline wrote:}the problem appears to be in the graphics implementation of safari which playing flash content exacerbates. once the corruption is introduced into memory it persists, requiring neither safari to be running or flash content to be playing to observe the glitch.

as the discrete graphics has its own discrete memory chips, it is not subject to the corruption error (n.b. i have not done any testing to conclusively say it will not occur with the discrete gpu).

the easiest way to flush the glitch out of graphics memory is to perform a complete restart. if the problem still occurs with dvd player or other software after a complete restart prior to using safari+flash on the intel chipset, then i will consider your hypothesis.

I am pretty sure I have experienced this after shutting the machine down and then starting back up and going right back into DVD Player without running Safari at all.

I have updated to the 10.6.5. but it just seems to be of no use. I'm not sure if flash accounts for those garbles. What i guess is that auto switch of graphics cards might have something to do with this annoying case.
I met with the mosaics about one month after my purchase and most frequently it happens when i wake up the computer from sleep. It also happens when browsing websites, though relatively less frequently. And most recently i found that launching Front Row could also make the display garble. I repeated the process and three out of five times this matter reoccured. In addition, when i pressed esc in Front Row and exited the application, the garbles disappeared. Later check showed the simultaneous auto switch of graphics cards from integrated to discreted when launching the program.
I have unchecked the option for auto switch and i would update with later observations. Nevertheless, it would be such a great sacrifice if only this way serves. I truly appreciate the longer last battery life of my MBP, which of course would be another story if discreted card is always on. I saw there was an update in the Mac section of support for MBP 2010 mid and the update is versioned at 1.3( if my memory works). However, it was not allowed to be installed on 10.6.5. So i have no opportunity to test it. Anyway, i hope Apple could do something to solve the problem, from the root.

From read through various post, I feel there are a few different problems people are experiencing, and therefore different causes. So I can only explain my situation: Connected to power, I had no problems, on either graphics card. But the nightmare became apparent on battery power. Someone around here lead to an application that sat in the menu bar, here I could see which card I was using, or force select one card over the other. If on Intel, all fine, but on Nvidia, screen would go crazy. If I could see enough of the screen to switch back to Intel, everything would become normal, otherwise I would have to force shutdown. After spending an entire day on battery power with 10.6.5, being aware of card switching, and on occasion forcing the machine to stay on Nvidia (just to be sure), with no screen garble whatsoever, I have been convinced that the update fixed my graphics problems. My RAM was factory installed 8Gb, my HDD is a 240Gb Mercury Extreme SSD from OWC. Hope this helps someone.

I have a MacBook Pro 15" i7 high-res glossy screen and I've been having these issues for a while.
For the full list of events and pictures, check out http://www.naemorris.com/mbp/

I bought it in April, had a dead pixel out of the box, screen was replaced then. In August I started experiencing graphic distortions and it got bad enough that I drove an hour and a half to the Apple store in October. They replaced my screen, bracket, hard drive, and logic board, then the week I got it back I started having more severe graphic distortions. Basically, instead of just the glitchiness, all processing functions ended and I got a weird pattern across the screen (looked like a couch from the 70s). After resetting PRAM like Apple told me to, I got the same issue but inverted. Apple then replaced my MBP (after two weeks of them not getting their act together). I just got this new MBP on November 4th and by the 10th I was experiencing graphic distortions again and now I was also getting kernel panics. I called AppleCare and after getting the run around for a few days, I was finally told last night to start a new user account and see if I could verify the issue there. I has distorted graphics in Safari, Finder, and across my desktop where before it was mainly only happening in Safari. Today, AppleCare told me to run a Capture Data program they sent me and return the results and they will call me in 2-5 days when the engineering team has gone through the information.
