Q: Anyone getting graphics corruption in OSX Mavericks?

So far this is working for me as well. It seems we are turning off one of the big "advantages" of Mavericks, which was supposed to speed up switching between apps. However, I haven't noticed any degradation in ordinary use to this point. Thanks so much!

Worked for me, but laptop ran very hot with the fan coming on a lot.  No surprise there as I run software that is memory hungry in the extreme.  So I reverted to the normal compressed memory state, but left the Auto Graphics Switching on.  So far (about a day), no reappearance of distortion.  Hopefully memory map has altered enought to get graphics memory into a safe place, if that makes any sense. Incidentally,  I know of mid 2010 laptops running Mavericks with absolutely no problem.  Whatever this issue is, it is tricky.

the screen corruption-artifacts issue also happened with my iMac (late 2009 model). i've since 'upgraded' back to Mountain Lion, because Mavericks is such a mess.

Distortion is back again with AGS on. I was hoping that turning off memory compression for a while would "fix" the problem, and it did for almost a day. I would love to go back to Mountain Lion, but that opens another can of worms.  When I try to do a full back up to the time capsule, it works on it for about a day, and then, just as the end is near, it starts to thrash, announcing that all of a sudden there is a lot more stuff to back up.  I'm still waiting for the fix from Apple, lol.

what i don't get is how/why such serious-pervasive bugs make it past beta testing / quality control. given that the display artifacts-corruption issue is so widespread, you'd think the Apple 'geniuses' would've caught that rather obvious bug sooner, before Mavericks went public. on my iMac, i noticed some display artifacts almost immediately after upgrading to Mavericks, although mine were comparatively minor, not as dramatic looking as many MBP users are reporting here and in other online forums. Mavericks was rushed out the door, without being rigorously-properly tested, imo.

Maybe there is an accountability vacuum at Apple now that Jobs is gone. 

Turning off the compression is working for me. Since 2 days not shut downs.
Had have shut downs in the last days about 3-6 times per day, sometimes with easy tasks like opening a folder in the finder.

Crashing MPB came back yesterday evening even with compression turned of.

Hi, I am also testing the no compression command. No, graphic problems until now! But, the MBP is really slow and hangs....

Hi - No graphics issues to report since I set compression off (as per Pehtis about 15 posts ago on the previous page of this discussion board).   Web pages seem to render just slightly slower in Firefox (v25).  Also, starting with Mavericks, when viewing files in the Finder's column view, sometimes it would take a few seconds for subdirectories or files to appear to the right of the selected directory.   This has increased to as long as 15 seconds since Pehtis's fix.

If the graphics issue reappears, I'll report here - Steve

So far on my Mac mini the graphic corruption affects "only" the icons on the Dock.

Some of them disappear randomly, other appear as multicoloured dots and one ore two appear normal.

But every time I restart the computer something new happens.

So the problem is not only affecting the Macbook Pro!

The Pehtis solution is still working for me, except that it makes switching between programs almost intolerably slow at times. Also, apps seem to take much longer to load, and startup is similarly slow. I am also experiencing the slow Finder effect mentioned above.

Just for grins, because I had run Mavericks with no problem for two months before this cropped up (maybe something in an update?), I tried turning compression back on. Bang! Instant recurrence of the pixelated halos around windows. So I'm limping along in 10.9.1 hoping Apple will get off their tails and get this fixed.

I'll admit I didn't read all 9 pages of this thread, but having encountered these issues and been participating in a different thread, I'd like to suggest a workaround.  Turn off Automatic Graphics Switching in Energy Saver.  It absolutely solves the problem, with the drawbacks of a hotter computer (fans may spin up more) and reduced battery life.  No performance impact like with disabling compressed memory, and no need to restart computer.

Hopefully 10.9.2 will solve this issue.

Thanks, suggested as the workaround many times in this thread.  Good to bring it to the front again.

display artifacts occur with iMac as well, with no AGS. the problem is Mavericks, it's a lemon.
