Green dots on screen (MBP 15")

Hello,
I just purchased my first Mac (MBP 15" C2D). I'm having a problem already....and I'm not having much luck searching the forums.

I'm getting little splotches of green dots on my screen. They show up on different parts of the screen when an app is open. IE.....when the browser is open, the dots are in the middle of the screen.....when the browser is minimized, the dots are over on the right side of the screen.

You can see the dots in the attached screenshot.

I'm sure this isn't something I can fix.....so my two questions are:
1) What is this? Is this something common in Macs?
2) Can I bring this back to the apple store (I bought it in a different state the day after Thanksgiving)....or do I need to ship it off somewhere. I don't have Apple Care (yet)....but this has to fall in the manufacturer's warranty.

Thanks in advance for your help!

Thanks for the tips.

Just some more info on the issue.....the green dots aren't static.....IE....they aren't in the same spot all of the time. If I move a window over the green dots.....they'll disappear.....but may pop up someone else on the desktop.

Also.... I only see them when the computer is fully booted....I don't see them when the machine is warming up.

Any thoughts? I can't find ANYTHING in any of my searches.

THANKS!

OK...now I'm really perplexed.
Per someone's recommendation.....I booted in safe mode....and what do you know..NO green marks on the screen.

Very interesting..

Driver Problem

Kind of sounds like a driver problem or a problem with Quartz. I had a similar problem with a Linux box of mine; re-installing the driver seemed to fix it. The only way I know how to fix that is to re-install OS X, but there probably a way to fix it without resorting to that.

After thought: I just occured to me maybe why it is happening. And still likely driver. The controller for the screen might be messing up the data for those pixels and memory allocation, and when you change the screen layout is changed that "anomally" is carried over into other pixels. If re-installing does not work, you might have teh hardware checked.
 
It is (correct me if I'm wrong) the graphic engine for the 2D interface in Mac's desktop environment. Does things that Windows couldn't even imagine or still can't with Vista (why you have to have one hell of a graphics card to run Vista)
 
An update for those who care (or who might have this problem in the future) :)

I took the MBP to my local Apple Store....and stumped three of the staffers there. They have never seen that issue. Since I was half-way through my 15 day grace period.....they provided me w/ a new MBP.

I haven't even cracked the seal on the new book yet. :D

Anyway....thanks for the assistance!

I've gotta admit, I haven't seen this before. I wonder what they'll do with it because it's most likely a software issue that might have been fixed quite easily. Meh, it doesn't matter. I'm glad you've got a new machine and I hope it serves you well. :)
 
AMD 4200/Geforce 7950gx2/2gb ram

Same issue, although i only get a single dot in my screen right in the center(when it started -2yrs after purchase-). I have not been able to find ANY INFO useful up to date. Changing the driver did not seem to work, the problem got so bad that my computer would not boot up anymore. The dots would appear in the boot screens and the screen would just be black and the monitor would turn off when the windows xp load screen would normally appear. I fixed the issue for about a week by reinstalling my OS and getting the most up to date video driver. I have seen the dots since then, but a restart has seemed to fix the issue temporarily. It seems to be a hardware issue, similar symptoms ive been told of overheating or under-powering.

PLEASE EMAIL ME with any questions or suggestions --- MEPHUD@MSN.COM ---
 
fixed problem

seriously, i had the same problem with my macbook when it was just new, it went away automatically but now i have it again after 2 years

so:
i figured it might be the video cable leading to the screen thats a bit loose?
i just gave 3 firm punches on the left side, above the speaker, next to the keyboard where you put your charger in,

i mean its alu, so it is probably strong enough for withstanding punches right?

3rd punch and is flooped away :D

say again that violence doesn't solve anything? :cool:
