Happens with an Intel NUC-5i5RYH (Core i5-5250U), Xubuntu 16.04, DisplayPort driving Acer 2560x1440 monitor.
Another workaround: Create a keyboard shortcut to "light-locker-command --activate". I use "ctrl-alt-C". Using the command "xset s activate" also works. When an unlock fails to restore the mouse cursor, using the keyboard shortcut flashes the screen and when reactivated the mouse cursor is visible.
