There is a slight motion on each of the dominoes & it is more noticeable when the footage is speeded up.
Yes this si a downside of the computational method used. Its cause d by numeric imprecision and how the forces work with stepping (it is NOT a solve its a simple iteration that may solve some parts perfectly). You should bake out the keys and then filter the noise out. Taking more sim steps also sometimes helps because the individual moves are smaller, so adjust the precision metrics.
If the surface of collision is flat consider a barrier constraint, its fare better than geometry.
It is also possible to make a velocity cuttof that rounds small velocities into 0, drag kinodf works the oppsite way around.
