Sorry I don't know floatcanvas (yet),
but found a similar problem in another drawing package and solved it.
It has to that when a drag is started (and moves fast), the first dx,dy
is lost.
# ************************************
# When drawing a new connection line,
# it takes a while to create the connection line,
# so when moving the cursor fast,
# drawing with delta-x, delta-y is not sufficient
# so here positioning to the absolute cursor position is done

cheers,
