The composite extension works well. Tabbing between
Activities is much zippier. Switching zoom level views
seems faster too, although the Home view takes a while
to draw the circle of Activity icons. The XO in the
center appears first, then a moment later, the circle blinks
in at once---visually pleasing but maybe not much
faster. I do see artifacts at the edge of the frame but
not that prevent use. I've added it to my .xsession.
