Unfortunately not! The polygons are never shown even if I decrease the distance to 1 or 2px. I expected to see polygone at some zoom level, even when I am supposed to see them. I may be wrong but even the cluster strategy is to regroup features that are close, I suppose to see polygons when they are quiet far away. Isn't it? One of the polygon in the link I gave in my first email is quiet big but never shown (the northest point, surrounding the 9).
