With my up-to-date version, I still get the smooth result when the I let Gmsh to choose the mesh. You can e.g. force it in your .geo file:
Mesh.Algorithm = 2; // 2D mesh algorithm (1=MeshAdapt, 2=Automatic, 5=Delaunay, 6=Frontal, 7=bamg, 8=delquad) I get the second mesh when forcing algorithm 1, MeshAdapt. The result you are getting is probably normal.
