Screen Glitch: OS X 10.8.3 Issue?

Over the past few weeks I've noticed a recurring problem which occurs in Preview and Terminal: scrolling vertically on my display results in garbled text. I thought at first this was Preview only, but it also happens in Terminal. Scrolling the same PDF in Acrobat Reader or in Safari instead of Preview shows no issues. It does not happen with Safari with general HTML web pages either.

If this were a video card issue, I’d expect to see problems with every program But if it’s a bug in some API used only by certain programs, then it could be application specific.

Attempting most screen captures or even scrolling back the other way redraws the content correctly (those bits are apparently refreshed). I have dual 30" displays on my graphics card and they otherwise are operating normally.

All of which leads me to posit a new OS X bug (10.8.3).

Yep, I also have developed this problem since going to 10.8.3.

System similar to yours by the sounds of it. Latest Mac Pro with dual 30" monitors.

I have noticed the same issue but I have seen it more in Safari (at least twice) when opening a new tab and once in terminal.

I am running a large display (NEC 27'') and Quadro 4000 so had assumed it was an issue with graphics drivers. Thanks for the post. I think this is worth following up with Apple.... Which I'm going to do right now.

MPG: with two people confirming, this sure sounds like an Apple OS X bug. It has made u sing Preview with PDF unusable for me.
