The desktop is no longer in a usable state any longer, you can't click on anything. Restarting the desktop with "systemctl restart lightdm" from console returns the desktop usable (defaulting to 1st compositor. - Same problem on my PowerBook 5,6. + On my PowerMac7,3 G5 with a Radeon 9650 Pro only the 1st one works + properly.
