I posted this in the news forum, but I thought I'd post it here too. The fix is working for me in Photoshop CS6! But now I'm getting a new graphics glitch; not nearly as bothersome, but a problem nonetheless. Let's say I'm running several programs including Photoshop. When I switch from another program to Photoshop by using Mission Control, I get a flickering glimpse of the the program window I'm switching from superimposed on Photoshop. It only lasts a split second but it's annoying. Anyone else having this problem? I should note that I don't get the problem when I switch from Photoshop to another program.
