We're running 188.8.131.52 and Artisteer 3 without any trouble. I'd double-check to make sure that the 184.108.40.206 important skin changes are still present in your theme.skin files. In your screen shot, the features don't have any border around them, and that's a symptom of those changes being missing.
It also might be a good idea to rebuild your skins fresh from the Artisteer 3 exports, using the latest Artisteer-3 base skin versions delivered in 220.127.116.11. I know Joe has fixed several Artisteer-related bugs in his delivered skins recently. It feels to me like Artisteer 3 + mojoPortal is finally at the "final release", so this is probably a good time to get your skins caught up if you can.
