On Linux, window contents are rendered behind a menubar

But only if the menubar wasn’t defined in the application code. Here’s a slightly modified example code I’m running:

import toga

def build(app):
    box = toga.Box()
    button = toga.Button('Hello world', on_press=lambda _: print("hello"))
    box.add(button)
    return box

if __name__ == '__main__':
    app = toga.App('First App', 'org.pybee.sample', startup=build)
    app.main_loop()

Here’s how it looks like to me:

Note that the button is behind the menubar (although no menubar was requested in the code). When I click on the menubar (including the Application or Help menu items), the button is being pressed instead.

I’ve tried this with a few GTK themes, including Arc-OSX-dark, Mint-X, Redmond and Adwaita, and in every case it behaves this way.

@joe733 If all goes well, we’ll release 0.3.0.dev20 this weekend.

Increasing the margin worked! Here’s what I get by clicking that second close button:

Thanks @friscodelrosario it works on Hera too.

Just curious when will 0.3.0.dev20 release be pushed?
