gnome-tweak-tool no options in "Titlebar Buttons"

[Florin Gherendi]

After upgrade from Ubuntu 14.04 LTS to 16.04 LTS, the windows title bar has no minimize/maximize buttons. In gnome-tweak-tool the "Titlebar Buttons" entry has no options to configure.
Running compiz flashback mode (I don't like the Gnome tablet style interface).

Computer is an Intel Core I7 with AsRock Z77 Extreme4 motherboard and integrated Intel graphics.
I have to mention that the distro upgrade totally broke the X so I had to purge it and completely reinstall Xorg, Ubuntu desktop and Gnome desktop (gdm3 was hanging, Xorg was "stopping successfully" according to log, and never start again, and startx was leading to indefinite hang, and no message in the logs was giving any clue)
