Detail: we look at interval exchanges defined as first return maps on the set of diagonals of a flow of direction $\alpha$ on a square-tiled surface: our main result is to show, by a combinatorial approach, that they are not rigid when the surface has at least one true singularity and $\alpha$ has bounded partial quotients.
