Q: Anyone getting graphics corruption in OSX Mavericks?
-
Sep 14, 2014 12:44 PMby Metalizer,your macbook pro model originally came with OS X 10.6 Snow Leopard
- people argue that this has probably been the best version of Mac OS X, to date
– in terms of performance and reliability.
You only need to use Mavericks if you want to use the very latest i Apps
like Garageband 10. Mavericks also has a feature called "sandboxing"
- designed to protect apps from malicious code. But more often than not, it
prevents a lot of third party plugins etc. from running and might stop legacy apps
from running.

Sep 17, 2014 3:36 PMby CaffinateMe,I am sorry to see this thread... I was hoping to find a solution and not commiserate with others affected with this problem. The issue of graphics corruption in various application windows has gotten substantially worse for me today. With no particular changes. It would happen occasionally before. I tried disabling the memory compression, but that had no affect. It very much feels like a graphics driver issue. I wonder if I an pull the ATI drivers from a 10.8 OS if that would help? Maybe I'll try another video card. Or if I have to, I'll downgrade back to 10.8, but that will be a real bummer due to the poor SMB performance on 10.8. I'm on a Mac Pro so the laptop screen setting solution don't apply to my situation either.

Much better than before where it would happen every few hours. If I have time ,I'll put my old video card in with a Yosemite beta and post back.

Oct 1, 2014 7:24 PMby mapsgal,So can we safely say that Yosemite is the fix and download the Beta version?
I am new to this discussion although I read from page 1 to pg. 15 and I feel for Steve H. who has been struggling with this problem valiantly for a very long time.
It just started for me 2 days ago when I downloaded a demo of Pixelmator and tried it out. Now I restart, reset the PRAM and every so often the problem start up again. Awful stuff. After hearing everyone else's pain with this problem I feel bad complaining about mine. I am on a 2009 iMac with ATI Radeon HD 4670 256 MB. I guess that's the problem too old too small a pipeline. I don't know if I can afford to upgrade the graphics card. Apple Warranty long since gone.
I will try a hard restart--i.e. unplugging and waiting. If that doesn't work, I am wondering if I should take the plunge and try out Yosemite. I am on the final leg of completing my book. Couple of more images to fix in order to mail this puppy off so I don't want to do anything too drastic like test out like beta test a new system. Clearly, something that makes heavy use of the graphics card kicks off the problem and then its hard to shake off...or so it seems from all these reams of pages of posts.
Good luck to All. I'll stay tuned too.

Oct 21, 2014 4:30 AMby Metalizer,Hi, I can confirm that Yosemite 10.10 has not fixed the problem on my
2010 15" model MBP 6,2 -
I am still getting sporadic patches of garbled text
on web pages & windows as well as distortion on images etc.
- but it seems momentary - once I refresh a web page for instance, it clears up.
I'm really disappointed that this issue has not been addressed - through one
whole OS cycle at Cupertino and even carried over to the following one.
It seems unprecedented for Apple to let us down, in such a manner.

Oct 21, 2014 3:49 PMby Barney-15E,You've ggot a Mac with a known graphics card fault from the factory. No update is going to fix it.

Oct 21, 2014 4:03 PMby goaliefight,Why don't you do a little more research... Yes the 2010 has had some hardware issues. This problem is not related to that. Many people have reporting continuing problems after replacing the system board.
This is an issue that for most people did not show up until the exact day they installed 10.9 (including myself). The most likely cause of the graphics corruption is memory compression that was introduced in 10.9. Disabling memory compression makes the problem go away. Additionally, the issue appears to have greatly improved with 10.10; however there are still occasional glitches. I can run problem free for several days (where before I could only go a couple of hours), but then a minor glitch will show up now in 10.10. The glitch will show up and then quickly go away when you do a screen refresh - this is much better than with 10.9. In this case, a software update made a BIG improvement, but there is still a minor underlying issue that needs to be fixed in the software.
There are two work arounds:
1. Disable Automatic Graphics Switching in System Preferences > Energy Saver
2. Run the following command in the terminal
sudo nvram boot-args="vm_compressor=1" -
Oct 21, 2014 5:19 PMby Metalizer,I have to agree with goalie fight on this one - besides, I bought mine from the refurb store
where everything is sorted and checked over thoroughly. I bought it well after the hardware issues
became apparent. So, in all probability I have a replacement graphics card.
Otherwise, the MBP is fine. I do notice that, when I launch a game, I often get a full
screen of a collage that momentarily appears & then disappears – fragments of web pages, emails, app windows etc. that were previously
closed - so it has something to do with memory cache. That seems to indicate
an OS or graphics driver problem.

My daughter has one. The logic board was replaced. Works just fine with Mavericks.
The Mid 2010 15” has got problems.
