Just testing out Mountain Lion, has occurred to me that it may not have fully supported the NVIDIA graphics as shown in these pics below... On launchpad, have a look at the Automator logo. On Safari, have a look at the Top Sites tab. There are some others that I have experienced, but didn't think to screenshot them. I recently got my logic board replaced, so my computer could not be the problem. Also, I am furious that Apple hasn't added support for the Airplay Mirroring for the 2010 MBP i7 2.66GHz.
