Indeed. BTW, I'm also using 2.12, GTK+ 2.8.6 and Cairo 1.0.2, so it
doesn't seem to be either of these in general, unless we have different
definitions of 'snappy' vs. 'dead slow' maybe... Have you tried
disabling sub-pixel AA in GNOME to see if it makes more of a difference
there than in KDE?

Mostly by watching the behaviour of the cursor and its surroundings,
e.g. watch for the cursor flickering when its surroundings are updated,
e.g. when scrolling the window beneath it. Also, when using
direct-rendered OpenGL, the SW cursor will disappear in the 3D window
and only shortly re-appear when you move it.
