I noticed a weird behaviour in my XFCE sessions. The DE starts fine and at a certain point, I still don't know what causes this, the XFCE desktop is transparently overlapped by the Gnome one.All my icons are duplicated, and the XFCE ones are unclickable. When I left click on the background, I get Gnome options and the Gnome desktop managing utility. Curiously changing the wallpaper in that utility has no effect on the XFCE session. While this is clearly a bug, is it a known one? Where should I check to see what's happening? Who should I report it to, if need be?
