Graphics error - 1-2 pixel line through QuickLook window!?

[allan.nyholm]

Hi,

I'm curious to hear if anyone other than myself has experienced this phenomenon with a 1-2 pixel line going straight through the whole width of the QuickLook window while viewing a bunch of images rather quickly?

The line is usually a mish-mash of the picture that I'm trying to view. A sort of distorted line.

I've experienced this not only in the QuickLook window but also while scrolling in Safari and Google Chrome - even on the desktop this pixelated line appears through the whole width of the desktop. It's always the whole width of the window not just a small portion of 5x5 pixels.

The line disappears just as quickly as it appears - though I've found an image of where I can reproduce this almost every time by switching to and from this in QuickLook.

I'm on a recent MacBook Air from 2013 with HD5000 graphics and of course Mavericks 10.9.0.

Is there anyone else who experiences this? Perhaps on other MacBooks or perhaps a desktop computer with Mavericks? I'd like to eliminate hardware issues.

Thanks to anyone who replies.
