Not finding the window controls where It used to exist is a very annoying thing. Only the Gnome Applications with actions in the title bar has this issue. Any pointers for debugging welcome.
Although not sure, I kind of believe that issues started after installing Something for Reddit from http://ubuntuhandbook.org/index.php/2016/10/reddit-app-something-for-reddit-ubuntu/. Could it be some problem with any dependency that came along with it?
Shell version is 3.24, Ubuntu 17.04
