Same here, and I am using ATI (Radeon X1950 Pro). Outpost tray icon is wrecked (as are Nero install icons) and I have folders of XP icons that all have very jagged black edges. Strangely, a couple of icons in the control panel seem to be displaying correctly, but I may be mistaken as I can't be sure how they looked before (I did not pay them that much attention). I have cleared icon cache, unregistered DLL and re-registered, but it's still the same unfortunately. I've noticed that you CAN'T check "show icons with all possible colors" in desktop properties. When you register this dll, that box is unchecked. Have you re-checked it after applying the dll register?
