This is a bit strange. Can you test this using a simple program
on the desktop with a mouse rather than touchscreen? I
want to know whether this is related to touchscreen jitter,
or a timing issue with the mouse up event after mouse down.
You might look at the code in nanox/srvevent.c and srvutil.c
to see how mouse events are handled and the child window
id calculated. Some debug/printf statements in that area
may also help, to see whether the up event has the same coordinates
as the down, for instance.
