Weird display artifacts after disconnecting from external monitor

I have the same problems. I thought it was a problem of the LG display at work, but I have several displays and macs too, and I have seen the graphic distortions with my MacBook Pro 7.1 running Lion and the Cinema Display HD 24".

The graphic distortions that I see are:

- The app switcher

- The spotlight widget

- The Apple menu

- Application windows

- Some of the text displayed

MacBook Pro

15-inch, Mid 2010

Processor 2.4 GHz Intel Core i5

Memory 8 GB 1067 MHz DDR3

Graphics NVIDIA GeForce GT 330M 256 MB

Software Mac OS X Lion 10.7.2 (11C74)

Confirmed with the same specs.

Not that this happens to me in the same manner but I'm really noticing graphic glitches when I use Google Chrome and Xcode 4 under Lion (said screenshot with Chrome http://cl.ly/1L023v1W2K0O393n231R) and I own a Macbook Pro 7.1 as well.

As I type this I revert back to Snow Leopard.

Exactly the same issue here. I have a MacBook Pro 15'' mid 2010 with a NVIDIA GeForce GT 330M.

My problem started with dark icons on the task switcher as described on the original post. Then a little while later when connecting to a secondary monitor I got for the first time the color distortions. This was in the task switcher, but also for whole application windows. Did not think much about it and thought and thought it was a glitch. Restarted the computer and te problem went away temporarily. Now I start getting the color distortion even without secondary monitor.

What's going on?

I have the exact same graphics distortions described above with a mid-2010 15" MacBook Pro when using a cinema display. Seems to have started with the latest version of Lion.

MacBook Pro 15" mid 2010

Cinema Display purchased Nov 2011

2.8 GHz Intel Core i7

8GB memory

GeForce GT 330M 512MB

Lion 10.7.2 (11C74)

I just installed 10.7.3 and now the graphic distortions are gone. The latest Lion update released yesterday (Feb 2, 2012) seems to have fixed it for me.

I had this problem and then it went away for a while. Using an MBP running 10.7.3 with an external monitor. Problem just presented itself again. But this time it's only when command-tab switching. The Menu bar isn't darkened this time.

So this still affects 10.7.3

I agree with the last comments, the problem is still present in 10.7.3 with the same specs.

I have filed a bug report with Apple, let's see how it goes but I think the whole external monitor management should be reviewed as right now is rubbish.

Funny that you mentioned this. After reporting the problem here (see above), it was ok for a while. Yesterday I was at a conference and was supposed to give a presentation. Once I connected to the projector the problem started again. Luckily it only happend during command-tab switching. I think I would have gone ballistic if all apps including keynote would have been affected again.

So the problem seems indeed to be connected with external monitors/projectors. Keynote presenters watch out for this problem.

Same problems here.

late 2009 MacBook Pro running 10.7.3

Happens on my Acer external monitor at work, and on my Dell UltraSharp at home.

Funny thing is right now it's fine, until I go into FullScreen mode in FireFox, then it goes wonky. Super weird that full screen vs. window would have this effect....

Hi,

I have the same problem, 2009 Macbook Pro, 10.7.3, it started with 10.7.1

I still dont know if its HW or SW problem.

Please, can anybody help

I have similar problems.

After reading this I put the com.apple.ColorSyncCalibrator directory from ~/Library/Caches into the trash, and then I switched users, and switched back to my standard user, and everthing is working for now. I will report more if the issue comes back. I didn't remove any of the other direcrtories because they were from non-apple related and non-display related sources.

My macbook pro model is MacBook Pro (15-inch, Early 2011)

Thanks for all of the replies.

Cheers,

David

Sorry for erroneoulsy reporting that the issue was resolved with OSX 10.7.3. I did not see any distortion at first so I thought the problem was fixed in the OSX update but the problem resurfaced for me about a week later. It seems to happen less often for me now though.

It turns out that the fix was temporary. I came back to my computer at work today and after working for a few hours my screen started getting wonky. Particularly, all of the finder windows became distorted.

I would prefer not to revert to Snow Leopard, as I enjoy many of the features of Lion. However, I am dependent on using multiple screens for my work, so I would like a fix for this ASAP.

Thanks,

David
