Seems like when you set the strokeWidth option in the freehand mode to something other than the default of 7, the location of the strokes you make on the canvas start to produce strange behaviour upon mouse button release such as appearing on a different location on the canvas or just completely disappearing (might be moving all the way off the canvas).
