Comment:

 I have reproduced the error but I am pretty sure is something at a lower
 level.

 I think the problem is in the implementation of the kinetic scrolling, but
 I am not sure.
 Attached is a test case. Not filled a bug yet, because I don't know if we
 have changes
 in this area, or if is all upstream now. (Carlos, can you confirm?)
 May be is related to https://bugs.sugarlabs.org/ticket/4060 ?

 To reproduce the error do:

 touch at the right of the screen, a circle is draw following the
 movements,
 when the touch ends, the circle is removed. logging show the events.

 If with one finger pressing in the right side, other finger do scrolling
 in the left side, and later touch ends, the "touch end" event is not
 triggered.

 If kinetic scrolling is disabled, the event is ok.
