Same issue here over the same distribuition Ubuntu-GNOME 16.04 LTS "Xenial Xerus" - Release amd64 (20160421). The system becomes laggy and unusable after several hours of idling. This happens all the times and looking through the System Monitor, gnome-settings-daemon is using up to 5 GB of RAM. I'll try to collect more info with Valgrind if i can.
