OpenGL screensavers, e.g. Keuphoria operate as expected. However when system is rebooted one (or more) copies of the screensaver are running on small forms (windows) tiled on the display. Can be stopped either with the close button or with killall <name> but come back on next boot. None of the other screensavers do this. Logging out and in does not cause them to come back, only a reboot.
