There is  R. Cauty paper from 2012 titled 'Un theoreme de Lefschetz-Hopf pour les fonctions a iterees compactes' which from what I heard was reviewed to establish a  correct proof of Schauder's conjecture ( or rather a generalization for iterates of f ), and will appear in an international journal.
