Does anyone have any solution for this problem? This is really annoying as I want to use Safari for the iCloud tabs and Reading list...
 
The problem seems to persist in Safari 6.0.1 and OS X 10.8.2 with the latest EFI update for yesterday...

Sad, I would really like to use Safari iCloud tab...
 
I'm not seeing anything wrong with MacRumors rendering. What should I be looking for? I see no lines, either black or white.

It is a CSS rendering error in Safari. You can see it here in my screenshot. The same page in Chrome does not show that line.

Not a big deal on MR, but some other sites display the same thing as a longer, dark line and it is annoying.

I am seeing the same glitches on my 2012 MBA. I just reported this to Apple, hoping that quantity counts. ;)
 
having the exactly same issue. mid 2010 15" macbook pro.

not that big of a deal though. 10.8.2 btw
 
I have same problem on my Macbook Pro Retina 15' (Mountain Lion)
Has anyone found a solution?

Everything was fine until 2 days ago.... I think it started occuring after the most recent ML Update...... I have an appointment with Apple this saturday.
 
Wierd Graphical glitch in Safari; seen it?

This is the answer...

This is correct. I only have noticed it in the MacRumors Headers of new articles.... When I disable the 'Automatic Graphics Switching' under Energy in System Preferences and refresh Safari my GeForce 450 displays correctly... it is an issue with the Intel Graphics 4000. (15" MacBook Pro Retina)

How do you accomplish this, I have no such settings in Energy panel.
thanks-

Same issues as others describe btw.
 
I'm having the issues mentioned on three separate rMBPs and it's driving me completely insane. I'm curious if any of you could post the major software you are using. Personally, I have Office 2011, Photoshop CS6, Chrome, Cinch and Beamer. I'm paranoid about Office 2011 since it requires shutting down Safari during the installation process; perhaps a file is getting corrupted? Fresh out of the box, Safari works fine, but within a day or two, the problems creep back up and ruin my browsing experience. I can't imagine Apple technicians are this blind.
 
Happens with me too. I have a MacBook Air 13" (latest model). The main website I notice the issues on is imore.com. As you scroll down, you'll notice vertical lines start to appear in the titles of articles... they sometimes blink or go away, some stay and sort of flicker when you move your mouse over them.

Chrome and Firefox work totally fine.
 
Same issues here. Latest version of OS X and reset Safari as well. Hopefully it gets fixed with the next update.
 
Mac Mini 2.3 i7, running 10.8.2. I removed the flash plug-ins and turned off Safari sync in iCloud settings. It seems to have resolved the quirkiness in Safari. Might not need to kill flash, but I felt better doing it anyway. When I need flash, I use Chrome since it's built in.

Hope this helps.

Interesting. I'll be sure to try it.

Flash is not installed in my MBA, yet I still get the vertical lines. :(

This is not fix the problem for me. The bug still here.
 
I'm SO ANGRY on Apple!!! For 4 fu** month this problem is this problem annoys me every day!

Can I change browser: yes, I can, but i don't want, because I have to use it.

I'm web developer and I can't work, i can't create and fix css code, because I see this ugly rough shapes and the extra vertical lines.

I'm fu** so angry, because I contact with Apple 3 times and today is 25 Jan 2013, after 4 month problem is not fixed. Did none of the staff or management Apple has Mac with Intel Graphics 4000? Does not anyone at Apple does not use Safari on Mountain Lion? So what the hell, no one pays attention to this problem???

I spend my last savings on this MacBook Pro, I always uses to see perfect quality in Apple products, but now I have this piece of junk.

I start think that if Steve Jobs was still alive, this would not have happened.
