Some further investigation: Joinings depends on zoom factor. If I draw the some trace while zommed in very much, joining is much better. Seems that endpoints of lines are not mapped to exact grid-points, but depends on screen/mouse coordinate. I think this should not be the case. Coordinates of entered endpoints of traces should not depend on zooming factor when grid is active -- endpoints should be always exact grid points nearest to mouse pointer.
