After about 7-10 plays, on return from the Play Again window, the decoration on the main window is lost.
If I have previously restored window decoration with gtk-window-decorator --replace then I get a message in the terminal similar to that shown in #5 above.
I'm not sure why you changed the summary from regularly to frequently. For my part I can 'reliably' cause this to happen as described in #9 above.
The program's main window has full decoration and a menu bar as shown here

as the game progresses a modal Play Again window is shown, as here
