If you run the hacks from the command line with the "-root" parameter, then they do (I think) and then you get direct rendering. However, the xscreensaver daemon seems to need to use the *real* root window. Don't ask me why - I do not know. All I know is what I've learnt from Mr JWZ: "The window that it's drawing on might have a different visual ID, if the ID printed by "xscreensaver-gl-helper" is not the default visual (according to xdpyinfo.) If that's the case, you can't run GL hacks on your real root window (only on a virtual root window) and there's nothing you can do about it" I'm assuming that Mr JWZ has a good reason for running on the actual root window...
