Experiencing screen tearing while scrolling text in OS X and in Windows everywhere.

I know this is years late, but my late 2011 15" MacBook Pro has this same problem. Tested fine in diagnostics too, which boggled my mind.

You really should start a new post for your problem rather then post it on the bottom of thread that has been dead for years.

This issue can cause this problem:

Apple Recall:

Run you serial number and see if you're in the recall pool. The Apple Store will have more sophisticated tools to asess your problem.

Screen tearing would definitely be a video issue.

I actually did that, but got the response from Apple saying that having 16gb of ram and not having a DVD in the computer is the cause of my video issues.......................................how does one even respond to such a boneheaded comment?

I'll probably be trying a different Apple Store once grad school is finished, though.

I have this issue with my late 2013 MBP. But it only happens intermittently and only certain apps are affected. If I restart or log out sometimes it will fix the issue, so it seems like it's a graphics memory issue? Very frustrating.

Does yours fall under the recall?

Maybe start a new post since it's confusing when you respond to an old one.

Recall is only for the Early 2013 and some earlier models and this is a Late 2013 model. But mine is still under warranty/apple care so I should bring it in at some point. However I think it started happening only after one of the OS X upgrades so when it first started happening a few months ago I chalked it up to a software bug which I hoped would get fixed, but now I'm thinking maybe it's a hardware issue, even though the diagnostics pass. My wife has the same model which she got around the same time and has the same issue.

My wife has the same model which she got around the same time and has the same issue.

So both machines are running 10.10.3? See the OP was also running Windows so that what I mean by confusing.

We have seen issues with this latest update and with Yosemite in general as to video artifacts. Like little tiled squares everywhere on a white screen.

I think that's a weird thing to be caused by the OS.

I've been avoiding Yosemite for this exact reason. I'm still running Mavericks and have actually just bought Mountain Lion because there's a few things squirrely things with Mavericks as well but maybe not enough to make me go back.

Since I work with Macs I actually have every OS since 10.2.0.

This started happening before Yosemite, so it was an earlier update. Unfortunately can't remember which one. Could have been a coincidence though. Just wanted to chime in here in case another example would help in figuring out the cause.

" Took my Mac in 2 weeks before the recall program ended."

Whew! just in the nick of time. Good to hear you got it fixed!
