Hi, RiP Steve. I have had problems with the graphics in OSX all the time since I installed Lion on my new iMac 27". That´ll say they are not present all the time, but I get little errors on the filemenu, dock, around the edges when I move a window, etc. Check out the screenshots: https://skitch.com/lifeform/f9gje/problems-with-the-graphcs-in-lion and https://skitch.com/lifeform/f9gpg/screen-shot-2011-10-08-at-03.52.33. These small little errors persist all the time when they have first occurred. Only restarting removes them (can´t verify that logging off and on removes them, but I forcefully removed all the processes via activity monitor earlier today without any luck). Any tips on fixing this? I am on a clean install of Lion via USB-stick and have downloaded all the latest updates. New iMac 27" as of july 2011. 3.1 GHz Core i5 and 8GB RAM.
