The issue just started popping up again. How annoying. It might have started happening again after trying to fix the jerky scrolling and jerky mouse when viewing PDFs in Safari by repairing my disk permissions in Disk Utility. Wonder if I can reinstall the update. Hmmm.

It's back for me too. Still have to logout and login again to fix the issue.
I had some time so I did a clean install of mountain lion and updated straight away to 10.8.1, worked for a while but it's back again.
Need a fix please!

I tried a SMC Reset and the problem appears again each time I restart my Macbook Pro.
The easiest workaround I tried consists in loging off after a reboot and loging on again. Then no more problem... until the next reboot.
I hope Apple will publish a fix soon.

I just got a mid 2012 macbook pro 15" and came across the same problem. Using 10.8.2. This issue seems to affect many users. Let's hope Apple realizes and fixes it with the next update!!
All the solutions published here are not definitive and Apple should take things in their own hands ASAP, IMHO!!

My 2010 Macbook Pro is doing the same thing, turning off the automatic graphic cards switching has been the only thing that helps but thats not a real solution. This has only happened since installing Mountain Lion. It happened on an install with a Time Machine backup and also after a clean installation.
I first noticed it in multiple CS6 apps, then it started happening in other apps.
Mostly posting to bump and raise awareness to Apple Devs.

I have the same issu, like some of you.
It's a real problem when I launch Aperture : I need to see real colors. My screens are calibrated, how am I supposed to work with such a thing ?!?

I opened a ticket at Apple support. They recommended reinstall MacOS X Mountain Lion using the appropriate option in recovery menu (using CMD + R at startup)
I applied this procedure but it didn't resolve the issue.
By waiting, the more adapted solution seems to be the closing and reopening of the session.
Hope they will reference the issue and publish a fix soon...

same issue with MBP 2012 (last one)....
...I thought I resolved the issue with an update of the NVIDIA driver (as described in the instruction), but after 3 days the issue was back again…
from the NVIDIA page:
Note: Quadro FX for Mac or GeForce for Mac must be installed prior to CUDA 5.0.36 installation
• There is a known issue in this release where forcing or allowing the system to go to sleep while running CUDA applications on 2012 MacBook Pro models with automatic graphics switching will cause a system crash (kernel panic). You can prevent the computer from automatically going to sleep by setting the Computer Sleep option slider to Never in the Energy Saver pane of the System Preferences.
• There is a known issue in this release where CUDA applications will not automatically engage the discrete GPU on 2012 MacBook Pro models with automatic graphics switching. To run CUDA applications, it is necessary to uncheck the Automatic Graphics Switching checkbox in the Energy Saver pane of the System Preferences

I have a 15" MBP (mid-2010).
Having issue since September 10 2012. No one can ever help at store level or call center level. Trying to do anything related to graphic design while issue persists is simply a no go. Restart sometimes works but only sometimes.
