If I remember correctly then they removed window theme from gnome-tweak-tool since it is now unused in GNOME - mutter use GTK+ theme. Here is commit: https://git.gnome.org/browse/gnome-tweak-tool/commit/?id=4db51ee4bcc4cad9bb9e6fb3ab68f44c3be6e317

It seems now Ambiance is always used as window decorator theme, even though I have configured to another theme. I believe Metacity 1:3.17.2-2ubuntu1 worked fine. I updated my Ubuntu and it updated Metacity and libmetacity-private2 to libmetacity-private3. Now things are broken, it worked before.
