Here are a couple of more patches for your bag of tricks:
This removes the usage of TransitionBox from HomeWindow.py. TransitionBox is
used to animate the Xo Guy while moving between zoom levels.
This patch makes transition from activities to the home box almost
instantaneous and removes the annoying flickering.
This is an updated version of your patch that also sets _RAISE_DELAY to 0 if
/home/olpc/no-frame-on-tabbing is present. It makes tabbing almost
instantaneous on my XO.
I have tried your hacks and I must say the frame behaves a lot better with
compositing enabled. I haven't run any serious memory pressure tests, but I
can have around 8-9 activities open before encountering OOM problems. No idea
what the previous statistics were.
