the "point of intersection of point and line" - tool draws the dashed circle at a wrong size.
One workaround is to change line 118 in file valentina/src/app/visualization/visualization.cpp to
QRectF rec = QRectF(0, 0, radius*2, radius*2);
removing devision by factor. It seems as factor is allready incorperated in the radius given to the Visualization::PointRect function.
