Problems with Video Display on a new Aluminum iMac

[drh64]

I have had this happen on two different IMacs and only when we run AC 11.

It seems to be triggered by Itunes running at the same time.

Has anyone else witnessed this before? Any suggestions?

The side remark above was off-topic, but I was getting pretty p'd off about the amount of time I was wasting trying to diagnose the reboot-on-wake issue with my Mac Pro.

Happy to announce that on Thursday, Apple released a firmware update for the Early 2008 Mac Pros which seems to have fixed the reboot on wake issue. It'll show up in Software Update for affected machines.

Parallels has been stable too, with only minor glitches.

Now if the video display issue can be fixed for everyone with ATI 2600 cards - iMac and Mac Pro - life will be good. 😉

One week after installing Leopard + 10.5.2 and all the updates - now I've got the graphics shit. On my MacBookPro C2D 2.33 !
(model 2,2 late 2006 with an ATI X1600 256 MB card)

The screen looks just like in this post:

It started while I was working in Archicad and browsing a picture folder in CoverFlow mode. The puter ran pretty hot.

Has anybody else seen it on a MBP?

I'm using a 17" MBP of that type and era without problems.

My 15" is behaving correctly too.

We have 5 computers in our office. We started seeing this same problem AFTER the Leopard update.

The problem ONLY appears on the 2 systems that use Archicad (Both are Mac Book Pros). Previously to the Leopard upgrade this problem did not occur. Both of these systems use a 20" external display. After we unplug the external monitor an open the laptop the display returns to normal.

It has been happening 1-2x's week on each system. They were also using the Archicad 3D environment at the time. Both use ATI,Radeon X1600 256MB.

I suspect it is a video driver problem. Would like to know of a fix if possible. If it were a heating problem wouldn't this issue have surfaced prior to Leopard update?

Interesting. My problem (as described above) happened when I had carried the machine home and only worked on the internal display.

It has never happened when I work on the external 24" Eizo. Which I do all the time at work. And I have the MBP closed which would make it hotter, I'd guess.

But of course it's a video driver issue. Leopard's drivers are obviously different from Tiger's. But that doesn't mean heat can't make a difference.

I've seen no fixes for MBPs. And Software Update reports nothing to download.

Apple "knows" about it

Thomas,

Yes yes yes, since upgrading to OS X Leopard I have the same graphic corruption as shown in the screenshot. It happens to me from time to time, no specific reason as far as I'm aware of. Above that 3D Open GL window keeps on flickering (AC10 + 11).
Latest software updates - I personally have no external display attached...

I have a feeling this is an issue that Graphisoft should contact Apple about. Lazlo?

Sorry, but that isn't the same issue.
