Oct 24, 2013 2:05 PM in response to drewexby ThreeD912,Yup, same thing happening here. Just upgraded to 10.9 Mavericks.
2010 MBP 15-inch, i5 2.4GHz.
Kind of odd that all that all of us have the same model Mac. I hope this isn't related to another issue described over here: http://support.apple.com/kb/TS4088
I just spent money to get my logic board replaced because of that issue, as the diagnostic test said I "passed" even though I was still getting kernel panics occasionally. Now I upgrade to 10.9 and see video artifacts everywhere.
Random video/graphics glitches appear all over the place after a while. Sometimes it's minor, other times it makes the system unusable as you can't see anything. Usually goes away again if you restart, but it's obvious there's some kind of graphics issue with 10.9.
the 2010 15-inch MBP.

Oct 25, 2013 2:25 AM in response to drewexby stjohnswell,Another mid-2010 15" with the same problem here. In my case, nothing particularly memory intensive - just surfing for a couple of hours - and there was over 400mb memory available when they started.

Oct 25, 2013 2:29 AM in response to drewexby clintonfrombirmingham,You have a faulty GPU as outlined in this Knowledge Base article -> http://support.apple.com/kb/TS4088?viewlocale=en_US&locale=en_US.
If you're within three years of purchase, the logic board will be replaced free of charge. If beyond three years of purchase, you'll have to pay for the logic board replacement yourself.
Good luck,
Clinton

Oct 25, 2013 3:52 AM in response to clintonfrombirminghamby Keps,Are you sure? I don't see how you draw that conclusion. The article says:
... may intermittently freeze or stop displaying video on the built-in display or on an external display connected to the MacBook Pro.
This is not what happened to me, or what seems to be happening in these screenshots.
I have not had any problems prior to Mavericks, and Mavericks has two big new features affecting memory: memory compression and variable integrated GPU memory. It seems reasonable that there are bugs in these features affecting older hardware.

Oct 25, 2013 5:24 AM in response to drewexby Anamesch,I had the same promlem. I had a .txt file in my home folder (don't know really how to call it) where only the "user", "developer", library", "programms" and "system" folders are included. The textfile included some weird slashes. I deleted it and now everything works fine.

Oct 25, 2013 10:13 AM in response to drewexby JC-King,Just to add another call to see if this can be addressed quickly.
The glitches appear randomly in what would be the shadow around windows. Occasionally it makes Calendar completely unreadable / unusable. Time machine seemed to trigger it.
No issues at all before Mavericks

Oct 25, 2013 10:50 AM in response to drewexby drewex,This started on maverick only. There is no problem with the hardware. Does anyone know back end settings for GPU or memory management.

Oct 25, 2013 10:55 AM in response to drewexby kevincennis,I tried editing /Library/Preferences/com.apple.windowserver.plist and setting ForceOldStyleMemoryManagement to YES, but it didn't help. In fairness, I actually have no idea what that's really supposed to do. I was just digging around and that sort of seemed like it may have been relevant.
Couldn't find anything else in other .plist files that seemed like it might help.

Oct 25, 2013 10:57 AM in response to drewexby ThreeD912,I probably shouldn't have mentioned the other issue with the 2010 15" MBP, as I think I ended up confusing some people with a possibly unrelated issue. Still, it's weird that this specific model is having all of these various video/graphics glitches.
Because the issue only seems to happen when on integrated graphics, a temporary solution I've found is to turn off "Automatic graphics switching" in the Energy Saver panel in System Preferences. Unfortunately, this will force the discrete high-performance graphics on all the time, and use more battery power.
While it's probably related to the new power management features of 10.9, I don't recommend people muck around with random plist settings or terminal commands as that could possibly cause more issues down the road.

Oct 25, 2013 10:58 AM in response to ThreeD912by kevincennis,Oh, weird. I'm having this problem on a 2012 15" rMBP, and it only occurs when I'm using the NVIDIA graphics.
For anyone following along at home, there's another thread that seems to be similar to this one: https://discussions.apple.com/message/23504487#23504487

Oct 25, 2013 12:14 PM in response to ThreeD912by drewex,I followed your suggestion on turn off "Automatic graphics switching". Of course no clue if it will solve the issue. Also bad part of all this is i cant duplicated it, pure random for me. I had my laptop open for 2 days with a lot of work done nothing happened, even repeating exactly what i was doing before. Not sure what causes the problem

Oct 25, 2013 12:36 PM in response to drewexby David_N,Yeah I also get the same corrupt display artifacts, they also have only appeared since the Mavericks update.
I've also got the same MacBook Pro model (15-inch, Mid 2010, Processor 2.53 GHz Intel Core i5, Memory 4 GB 1067 MHz DDR3, Graphics Intel HD Graphics 288 MB).
It's definately a software issue. The temporary fix that corrects my display is the > System Prefs > Energy Saver > Untick/re-tick "Automatic graphics switching". It instantly corrects the display. It's a pain in the *** but better than a reboot.
Hopefully an update fix will be along soon.
