</span>Then why did XFCE on the same hardware scream? Are you saying that<br>
OpenGL is the fault for the suckiness? This was the same machine. Same<br>
audio stream and sources, same screen, just logged in with GNOME 3<br>
session in one case and XFCE session in the other. Rocked with XFCE and<br>
sucked with GNOME 3.<br>

</span>I don't know what XFCE is using but it's beating the pants off GNOME 3<br>
in that environment.<br>
