@gabby, just installed catorize. Are you sure you don't have custom transitions? Best way to notice is that when you open the appmenu the background image remains "bright". My transitions shows the changed fade-in effect only when opening first level of app-icons. Second level appears with default-styled animation (when you open a folder created by catorize). Just want to make sure we're not trying to debug something that doesn't need debugging I can change the transitions so that also second level of apps appears with same effect as the top level.
