Since installing OS X Mavericks on my Mid-2010 Macbook Pro, occasionally there is distortion on the display- lots of coloured lines

That sounds like a graphics card issue. Run Apple Harware Test

Also, I'd bring it to the Genius Bar and let them diagnose.

Same problem here, Macbook Pro Mid-2010 15" i7 processor, since the firts time i run Mavericks after updating from Mountain Lion, display start to show colored lines... or things like the one on the photo...

I have exactly the same problem (same Macbook pro configuration as well). Has anyone come up with a long term solution yet, or should I just restore to Mountain Lion until this is resolved? I'm a teacher; I can't have my screen all wonky while I'm trying to teach.

I think is a different issue since the video is not lost, and it has to be something related with Mavericks since the problem was not present on mountain lion, and start immediately after the first run on Mavericks.

Very few saw the problem on Snow Leopard. It wasn't until the Mountain Lion upgrade did it become apparent. Snow Leopard did not drive the video card as hard as Mountain Lion. If Mavericks is driving the card even harder, then it is possible.

If you don't have a nearby Apple Store or Apple Service Center, then I guess hope is all you have. It's a known defect. That description may be the only artifacts they were aware of at the time of the article.

You are right, i am in Mexico, i will try to check with the phone service center about this. Thanks

If you do manage to get to a place that can check it, make sure they run the test that is specifically for that issue. If they run the normal checks, it won't find anything wrong. Take a printout of the article with you.

The offer was only good for three years from purchase, but given that it doesn't seem to appear until you upgrade to a more demanding OS, you might be able to convince them to fix it for free if you are already beyond three years. You'd likely have more luck at an actual Apple Store as opposed to a Certified Service Center.

I have the exact same problem with my macbook pro, which is also a mid-2010 model. This began to happen frequently after I intalled the Mavericks.

This also happens on my 2010 macbook pro, but only when the intergraded graphic card is in use, if I switch to the discrete one with gfxcardstatus, it goes away.

Im having the same issues. I will be going up to the Apple Store soon; If anyone has any luck, reply.

Having the exact same problem on my MacPro 2008 with nvidia graphics - this is definitely a Mavericks issue ! Never had it before updating - now it crops up daily - disappears as soon as I go to the "color " tab and re-select my profile. Got two screen setup and this ONLY occurs on my Eizo CG245 which is hooked up using DVI - on my second monitor - and HP LP2475 - which is hooked up using displayport it never occurs -

I get Red Lines.

Something related to Energy Saver. Automatic Graphic Switching.

Visiting certain websites on Chrome or using let say adopbe products makes my screen go crazy.

I will try to downgrade to older OS.

Same problem. I have a 15-inch, Mid 2010 2.66 GHz i7 with Intel HD Graphixs 288 MB.

Seems like this would be an unhappy coincidence if all of our graphics cards went out at the same time immediately folloing installation of Mavericks.
