Snow Leopard Graphics Corruption

Ok, so I didn't have them run diagnostics yet, because I think I found a solution. I archive and installed 10.6 again (which is super easy, just pop the disc in and hit install, it does it automatically).

Then I manually updated each update to 10.6.1, 10.6.2 and then did software update to get 10.6.3 (not on apple's site yet). I'm pretty sure there's something with the 10.6.2 combo update that came through software update after my last clean install (had a failed HDD) that caused the glitching, since my first install of 10.6 back in the fall never had the issue (always got a single update then too).

No glitches all day yet, and i've tried to provoke it a few times.

I had the same problem with my late 2007 (macbook 3,1) and SL 10.6.2
in the end I had to downgrade back to 10.5.8 because these glitches beame very annoying

any word from the developers regarding this problem? I would really like to update to SL again

I know this doesn't really help but I would also like to voice my concern over this issue (as I am having the same problem on a Macbook3,1)

Mine's a white iMac 24inch. 3GB RAM which is the maximum. It sits on the kitchen wall and we use it mostly as an entertainment centre: web, music, photo's and TV (with EyeTV) in full screen. Since loading Snow Leopard (upgraded from Tiger where everything worked fine but I wanted iMovie09) a couple of weeks ago the corrupted graphics are a regular feature.

Last night it had all gone crazy. I usually restart it but couldn't be bothered and just left it be. After a while the screen (only) went into sleep mode. Came back and woke it up and it was all OK again.

Bob.

Sometimes black lines will appear on the dock and/or the menu bar will go black. i have run a hardware test and it said that there doesn't seem to be a problem with the hardware.

OK I've got a MacBook 4,1; it never had Tiger on it but I've ran every update since Leopard prior to upgrading to Snow Leopard, then run every SL update & I've never seen this since SL's release date.

So what, specifically, do we know about this? When it is occurring, on what models, is it isolated to Intel GPUs?
I personally I have not been affected but I'm curious to gather all the facts & see if we can't get a grip what it may be. Hopefully this will help give us a solution.

What makes the problem show up is the presence of Intel GMA X3100 integrated graphics chip.

Well from what I understand it seems to be effecting MacBooks with the Intel GMA X3100 integrated graphics chip, running Snow Leopard. It could have something to do with the Intel X3100 driver in Snow Leopard. It appears to happen randomly, but it occurs more frequently when the MacBook is trying to preform intensive tasks such as viewing YouTube videos or running a Virtual Machine etc.

Er hello?

I'm the white iMac from a couple of posts up. I'm guessing this happens on a lot more than MacBooks but this is a MacBook thread hence the preponderance of MacBook users. I only found it because of the search terms I used. My symptoms are identical. For me it's after viewing video or TV material in full screen.

Sorry I got confused because you have on your computer model info, G5 processor dual 2.3 Mac OS X (10.4.11). What are the specs on your iMac? specifically what GPU does it use?

was that previous snapshot taken in 10.5 or 10.6?

10.6
after that i reverted back to 10.5.8

When you where using 10.6 did you happen to have the Flash 10.1 beta installed?

no, it also happens on clean install so I believe the problem is not in the software but in the drivers
