[Sugar-devel] testing composition for speeding up graphics performance

I've just tried xcompmgr on my XO with 0.82 (f9).

I also see significant perceived performance improvements when sliding
the frame and especially when switching windows.

I have however noticed some artefacts on the top of the frame and the
edges of Terminal (the activity where I started xcompmgr). They
disappear after I restart an activity, though.
