I'm using Xubuntu with the panel at the bottom of the screen and I have fixed the scroll problem by removing xfce4-indicator-plugin and indicator-application (I also removed all Unity indicator-* packages). This way Xfce can directly use the notification area. Another solution was to use dbus-launch nm-applet http://askubuntu.com/questions/449658/networkmanager-tray-nm-applet-is-gone-after-upgrade-to-14-04-trusty#comment806285_458800
