Actually I think the major problem was immediately after 22 sec point. 
When during movement the X or Y coordinates of 2 (or more) touch points are momentarily overlapping, quite often they are swapped and the mirror touch point is "sensed"/presented instead.
In 3-point touches (using faster apps) where X-Y crossing is more likely, it is a constant problem.

Yes, I realize that. Other apps are much better in this respect, but this was the only app I could find that does not want to access anything else on the laptop ::) and it was fun :)

Talking about speed, the XO-4 is still showing (and behaving) as a single core.
I think at some point just before the downsizing/resolution of XO-development team, Wad reported some progress on bigLittle. Anybody knows if this is still pursued by anybody?
