Since upgrading to 10.7.2, I've noticed a graphics glitch with the application switcher (cmd+tab). Randomly the icons will be darkened or distorted, or when quitting an app via the application switcher, I'll notice the glitch flash when the application fades out upon quit. A logout/restart solves the problem temporarily, but it seems to arise shortly thereafter. MacBook Pro Mid-2010 NVIDIA GeForce GT 330M 512 MB 2.66 GHz Intel Core i7 8 GB 1067 MHz DDR3 It is the model with the graphics switching, so I'm not sure if that is related? Any help or suggestions would be greatly appreciated. Thanks! UPDATE: I would like to add that it's happening when my MBP is plugged into an external display. I currently go from plugged into an Apple Cinema Display at home to a Dell display at work. It appears to have graphics issues coming out of sleep on these monitors.
