Another replica of this issue over here.
One could agree with #Omer Akram about the nature of this bug. Most
likely to be a clash of unity stuff which actually runs (!!) with the
Gnome Classic stuff I'm currently using in my session.
I chose not to use Unity, I logged in with Gnome Classic. Then opened
Oracle SQL Developer like #m1fcj did and after saving and closing a
script (closing a tab), all the window decorations went away... and the
workaround from #Carlo de Wolf does not work happily 'cause the gtk-
window-decorator does not take into account the theme settings (yes, I'm
kinda pushing it, if one wants to work then the idea is useful).
