I've just updated from 10.8.2 to 10.8.3 on my mid 2012 rMBP. It's intermittent, but any time I move the cursor when in the Mac App Store (full screen mode) the graphics look like digital noise (don't know how else to explain it - image attached).

This is my first post so apologies if it has already been discussed.

Thanks in anticipation,
Joe

That looks pretty bad, if it were me I'd probably do a fresh install. If that doesn't work you might want to take your computer into a shop. Looks like something you could probably get a replacement for.

There's also a new SMC update that addresses some graphic card issues. Make sure you update this as well if you need it: http://support.apple.com/kb/DL1559

I would also try a SMC and PRAM reset to see if that fixes your issue before re-installing the OS.

SMC reset:

Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.


PRAM reset:

Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
