Kivy crashes when making fullscreen on OSX Sierra

I have a basic Kivy application (see below) that launches, but when I fullscreen it Python crashes with a Segmentation Fault.

Steps to reproduce:

1. Start a basic Kivy app
2. Click the ‘fullscreen’ button on the OSX window controls
3. The application crashes, and OSX offers to report the bug to the Python authors

Code:

#!/usr/bin/env python3

from kivy.app import App
from kivy.uix.label import Label

class Visualizer(App):

    def build(self):
        self.label = Label(text='Please wait...', font_size='50sp')
        return self.label

Visualizer().run()

Let me know if I can provide anything else useful!

Great. Thanks for posting back 😃

My kivy was using pygame. When I installed the latest kivy, it used sdl2 which solved the problem.
