If you add a VerletGrid and a RectangleConstraint with the same size to the simulation. Spheres act very weird. I think this is because the VerletGrid rounds its Grids to the lower number and won't fill the entire specified area.
Possible fix: give VerletGrid one more row and collumn instead of one less
