Sorry, I don't have a fix nor an explanation, but I used to notice this along with the slow menus that you mentioned before but it seems to have dramatically improved when I went from RH 9 to Fedora. I'm running on an old system (P-III 500 512 MB RAM, an old Riva TNT2) and any "GUI lag" that I used to see is gone. It used to be one of my biggest pet peeves with working in X before FC1. -b
