Observed this bug on Xubuntu 16.04 (installed yesterday from http://cdimage.ubuntu.com/xubuntu/daily-live/current/xenial-desktop-amd64.iso.zsync ).
New account, quickly customized.
Observed after locking screen for the first time with 16.04.
Never observed before (on 15.10, 15.04, 14.10 with same hardware), but on those I used xscreensaver because of a bug with lightdm.
