Your test case of showing "Scores" makes it a multi-window GTK app. So I think you will find this is bug 1445543.

I've not yet investigated what's unusual about this window. Some other dialogs (e.g. "About") work fine. Also relevent to focus handling, despite being able to set focus to the main window it doesn't respond to input - with the "About" option above, closing that window enables it. With the "Scores" example it isn't possible to close the unresponsive window. Looks as though the toolkit stops responding to input events - they are being received by the client process.
