I don't use compositing on the desktop but I'm having the same lousy performance after upgrading to the Jaunty alpha. My system has Intel's 965 graphics.
I attempted to run Sauerbraten which normally gets about 45 fps and got less than 1 fps. I also attempted to run Google Earth which threw an error about running OpenGL in software but, while slow as all hell, at least didn't lock up when I attempted to open my image overlays and shows all the letters and numbers it's supposed to.
