gdm is a display manager (I'm using xdm, BTW). The default gnome window manager should be metacity (you can check that with "ps uxww |grep metacity"). Anyway we are obviously using totally different window managers, but the problem is the same. Sounds like either an X server or driver issue then... As you are running testing (lenny here), can you try wether the delay occurs with the open source drivers (radeon and radeonhd IIRC) as well, please?I'm encountering the same issue on a single head setup (never used Xinerama). What window manager are you using (ion3 for me)?I am using gdm, in an as-is apt-get-install-debian-testing-with-Gnome-installation.
BTW: I already tried enabling double buffering, but it made the delay even worse.
