Q: safari rendering issues

I've got the same issue with both graphics cards (I think; definitely discreet, can't test integrated right now, but I'm pretty sure it's broken too). I've got a late 2011 MBP, 15", 2.2Ghz, high res.

I am experiencing similar rendering issues in Safari. I often see it happening when I am in Gmail or other sites when animation is triggered through JavaScript or CSS3 animation - like when a panel slides in.

It also occurs when scrolling up and down where elements get misaligned.

I'm experiencing the same rendering or whatsoever issues in Safari. To verify John+Apple's hypothesis, I've installed the little program "gfxCardStatus" too, where you can manually switch between the intel chip and the dedicated AMD graphics card. It really seems to happen only for the integrated Intel HD 3000 graphics card in my late 2011, 2,2 GHz, HiRes MacBook Pro. So I'm happy that it seems to be an issue with the 10.8.2 update rather than the integrated graphics chip!

I've noticed the same issue for months now in Safari. I never installed Lion, but have installed Mountain Lion so I can't compare. This is a highly annoying bug and seems to mostly be noticable to me when I'm typing text. It's as if the text is sometimes deleting itself or slow to appear sometimes. This is clearly a redraw bug. I've noted that there's some issues with graphics as well, especially with menus, loading, etc. Software seems to be solid other than the Reminders not showing any of my old To Do's when I migrated from MobileMe to iCloud (still awaiting higher level technical support on that for over a month now).

EDIT: Just snapped this screenshot after I posted my reply to the original post.

Same here. Annoying artifacts since upgraded to ML. mid-2010 MBP.

This seems to be fixed in the latest WebKit nightly (r130582 as of now).  If this is annoying you enough, you can download that at:

As always, with nightlies, you may encounter some new bugs.  Your mileage may vary, and I will not be held responsible if it strips the paint off your car, turns into a wolf and tries to eat your grandmother, and converts your computer into a George Foreman Grill.  You have been warned. 

Correction.  Current WebKit fixes many of the corruption problems I was seeing, but it does not always fix the "text disappears and reappears randomly while typing in certain forums" problem.  So apparently there's more than one bug involved.

Same thing here.  Gmail, Facebook, Twitter seem to be the worst.

I am also having this issue on my Mac Pro since I reinstalled 10.8. I never saw it on my previous install, which was an upgrade from 10.7 and 10.6.

My Air is also on 10.8 and I haven't seen the issue on that yet.

This display problem in Safari seems to be a bug with the JavaScript engine.

I've got the same problem..

Same problem here with some websites using Safari 6 in Mountain Lion 10.8.2.

I'm also having this same issue. MBPr bought a month ago, Safari 6 and Mountain Lion 10.8.2.

I wonder how it really can take so long for Apple to fix this? After all, this is happening with their latest hardware together with their latest OS and browser. Not happy about it.
