I have a MacBook Pro Retina and it too is freezing multiple times per day after the 10.8.2 update. I don't get the screen corruption, but the display locks up and the only thing I can do is hold down the power button.

Mine was working all day then just a couple minutes ago everything started to freeze. I too applied the 10.8.2 update which prior everything worked perfectly. I have a 15" retina as well.

after a very long process, i am finally up and running an the problem is gone....i ended up erasing the hard drive, installing a clean version of mountain lion 10.8.2 through recovery at startup, and the problem has not presented itself since installing the os, and restoring my time machine backup....it was long for me because my time machine backup was corrupt, but once i figured out how to get it into the disk utility and hit repair all is well...
so i would try that for those that have the issue...back everything up, reinstall the os and restore....

Yeah... that's not going to help me much on my MBPro
10.8.2 failed when installing from the App Store... So I went and manually downloaded the installer for the combo update.
After installation, it came up with a VERY long attempt at TimeMachine (capsule), after which, it said that the backup was flawed and it was going to start a new one -- OK --
My old backup was erased, the TimeCapsule drive was wiped, and it started a backup which NEVER finished. The machine is now completely unstable. Finder quits every 2 minutes... sometimes never to relaunch.
I know HOW to put it into target mode, and copy things to an external disk, but this is the messiest update I've EVER experienced, and I'm a Mac guy since 1986. The prospect of reformatting, and reinstalling everything is just making me blind with anger.
What a mess.

same screen corruption happened to my MacBook Pro (model from mid 2011) after upgrading to 10.8.2; I reinstalled the operating system overnight, with no success; then I tried zapping the PRAM (Apple+Option+PR at startup) and that solved the problem; no idea what caused it, quite a scare.

My 2011 i7 iMac feezes once a day since I updated to 10.8.2
Only solution is a hard restart.
This is frustrating. I had no problems whatsoever before 10.8.2
I noticed that when it wakes from sleep, sometimes the Time Capsule menu icon appears frozen as if the crash had happened when attempting a backup. I wonder if it's related. After restarting my iMac, Time Capsule backups seem to work fine.

I had the same problem on a 2008 Mac Pro after 10.8.2 (update or clean install, it didnt matter).
Turns out that it doesnt want to play nice with my Logitech mouse. Took that out of the USB port and used a spare one I had and all is now fine.
Long shot for anyone reading this, but try removing your USB gear to see if any are giving you grief.

Why should we do this? This problem significantly affects my productivity. Not only this problem but also many other problems have been bugging me for a long time. Apple genius is not helpful at all. I regret my decison to move to Mac a few years ago. I will find a way to go back to Windows without much interruption.

Since the 10.8.2 I AM getting screen corruption, but unlike that shown. Seems while adjusting for the Retina display something went wrong. I've cleared cache, rebooted, reset PRAM, safe booted, manually applied the update. Nothing helps except when I rotate my display 90 or 270, guess then the horizontal pixel address is off screen.
It's not my monitor, screen shot would not show the corruption. Also, I booted into an old Snow Leopard, no artifacts!
Glad that it's just an annoyance, hope it doesn't burn my phosphors and that Apple sees fit to fix the issue.
Also wish that Apple would provide an official mechanism for reporting such things, assume they monitor these forums and take note of issues.

I had exactly the same issues as you, look here, screenshotable Pixel failures:
and like in the beginning of the thread, a freezed and scrambled display:
I am sorry to tell you that only a new Montherboard fixed the Problem. Your GFX Chip or MainBoard is failing. It's some kind of GPU-heat/Heavy Load related Problem. In my case it only got worse until i had to let them replace my MainBoard.
