Graphics glitches occurring with the GeForce 9400M?

Has anyone seen the same type of graphics glitches occurring with the GeForce 9400M in the new MacBooks that occurred in the MacBook Pros with GeForce 8600M GT?

The link to that previous issue is here: http://apcmag.com/appleacknowledges_macbook_pro_graphics_glitch_offersfix.htm

When viewing web pages with both Safari and Firefox, the page gets corrupted when I scroll down with the trackpad (this does not happen when scrolling with arrow keys). Any type of animation or video on a page is also really jumpy and flashes in and out.

It sounds like this was a hardware issue with the graphics card in the last version of the MBPs. Has anyone seen this issue in their new MacBooks?

MacBook 13" (Late 2008), Mac OS X (10.5.5)

Hi there,
the same issue on my new MBP Late 2008. First, it happens in Safari, then I tried Firefox and there it was too. I switched the graphics to the second GPU (the better) and it seems the problem were solved. Back on the mobile GPU it never happened again.
I've never tried, but I think the problem occurs when to much Apps are opened and the Mac runs out of memory. The logout for switching the graphics gave the memory back and the better GPU has it's own memory.

Count me in as well. Seems to be MUCH worse in Linux, but it is happening in 10.5.5 as well...

The fact that it is happening in Ubuntu has me slightly more concerned than if it was just OS X. If it was a driver issue, you wouldn't think it would follow to another OS unless the Linux drivers were mediocre as well..

There have been a lot of views of this thread. I am assuming Apple is working on this. Has anyone called support?

I have experienced a similar problem with my MBP 2.5G (late 2008) edition, wherein the display blinks momentarily. To analyze the issue, the glitch/ blink was vide taped and watched in slow motion. I found that the glitch is really a corrupted video signal followed by a partial/ complete blackening of the screen. The problem only occurs while using the GeF 9400 M mode in OSX and is never evident when using the 9600 processor.
Further, the problem is random and independent of memory or processor usage.
In my analysis, it is a hardware bug similar to that with 8600 processors with the only resolution of replacement of the MBP. Please reach out your nearest Apple Store ASAP, in case the problem is observed.
