Graphics glitches occurring with the GeForce 9400M?

Update: Tried the daily maintenance scripts in MacPilot and cleared history in Safari, but haven't seen any changes yet. Have to get Onyx and see about those cache cleanings.
-- But here is one weird thing: When I visit the Norwegian newspaper Aftenposten ( http://www.aftenposten.no/), there are no screen glitches even in Safari! Maybe it's because the front page is anti-cache and redraws from the server all the time... (like, if I lose the airport for a few seconds, the Aftenposten page will go "page not found"). So, obvoiously a cache thing, and connected to the trackpad scrolling (no glitches if I move the scrollbar on the right, like in the old days).

Same problem - 844 is in the serial number.

Still no word on a fix or a technote of any kind?

Uploaded a screenshot here. Seeing the same problem as described elsewhere:

I talked with apple support and they had me restart my hardware. To do this,
1) shut down your computer
2)press the power button and immediately hold down option-command-R-P
3)wait until you hear two chimes ( a couple of minutes) and then release the key.

It is working so far but time will tell if that worked.

I used Onyx to delete various cache files and then restarted. The glitches have disappeared and not come back during the last 4 days. I'll have my fingers crossed. Did not do the PR (parameter Reset) thing yet, but nice if you can fix it that way too.

Hmm, it came back today after 5 days. So I did the same cache delete w/ Onyx again (only the ones Onyx suggests by default). And restarted with PR (parameter reset - Cmd/Alt/P/R). Now it's fine again...

I have reset my PRAM, cleared my cache files, nothing works.

I still have this problem in iLife, dashboard overlays, progress bars, etc, etc, etc.

VERY annoying... not sure what to do, maybe should have kept my old mbp for awhile longer. shrug

Whomever was asking about serials, mine was "844" so 08 machine built in the 44th week if that helps anyone at Apple. I plan to call in to the support line and let them know what is happening. I would suggest everyone do the same to make sure Apple is aware of this issue.

Interestingly, mine is also 844. The problem got a lot worse after 10.5.6.

The main problem is in Safari – interestingly, it's less noticeable but still there in Webkit nightlies – but can show up in other applications too. It happens more regularly with horizontal scrolling than vertical, too.

Very annoying.

Further to this, I've noticed another application that reliably produces distortion.

Football Manager 09's 3D match view flickers and has the same horizontal distortion patterns as I see in Safari all the time. However, like Flash video, for me it's only when the app is running in a window – as soon as I fullscreen it, the distortion goes away.

FWIW, I have a week 41 Macbook 2.4ghz and I've NEVER had a single graphical glitch since the day I got it. I've updated the software as it has become available but never had any glitches at all. I've run VMware/parallels and never had any glitches with that either. Definitely not in Firefox/Safari.

Any thoughts if it's a production issue?

Mine is 845. Same problem.

The picture you posted is EXACTLY the type of thing I am seeing in my Macbook. Serial number has 842 in mine. Generally, same types of experiences as other posters. Clear caches, etc. but problem just comes back.

I also have a week 41. All is clear on my MB.

Same problem here (serial W885). Between the graphics corruption issues and the terribly designed spacebar (seriously, the shoddiest piece of junk Apple has ever released) I am pretty ****** about this Macbook.

Is anyone at Appleeven listening?

(ah, there's that ^ crap-tastic spacebar issue in action)

I have noticed that if I am plugged in to power, the problem is either significantly diminished or gone completely. I just did a test: scrolled on this very web site discussion group topic and got the graphics corruption. Plugged in the power adapter, and move the corrupted part of the screen up just enough to force the screen to refresh coming back down - corruption gone. I repeated this several times, disconnecting and reconnecting the power and results were the same. Whatever the problem, it's related to whether the mac is plugged in.

After noticing that the graphics corruption is way worse when the Macbook is unplugged, I changed a a setting in the Energy Saver control panel - unchecked the "Slightly dim display when using this power source" on the Battery tab. Ran Onyx to clear out caches, etc. Rebooted. I know that some posters note that the problem clears up for a few days after using a tool like OnyX or Cocktail. But, as of now (< 24 hours since doing this), I am not having this issue even with the Macbook unplugged.
