Kivy Window doesn't recive first touch when unfocused

Question

Each time I tap my mouse anywhere outside kivy window and get back I have to tap the window twice to recive on_touch_down event. Is it possible to recive that event when I tap for the first time? The only event I recive is Window focus. My idea is to catch, if possible, touch from window argument and call on_touch_down. OFC I'm open to any solution to that problem.

from kivy.config import Config

Config.set('graphics', 'multisamples', '0')
Config.set('graphics', 'width', '400')
Config.set('graphics', 'height', '400')

Config.write()

from kivy.app import App
from kivy.lang.builder import Builder
from kivy.uix.boxlayout import BoxLayout
from kivy.core.window import Window


kv = '''

MyWindow:

'''

class MyWindow(BoxLayout):

    def __init__(self, *args, **kwargs):
        super().__init__(**kwargs)
        Window.bind(focus=self.window_focus)

    def window_focus(self, window, focus):
        print('WINDOW FOCUS', focus)
        if focus:
            # is it possible to get touch from window and call on_touch_down?
            pass
            

    def on_touch_down(self, touch):
        print('TOUCH DOWN')
        return super().on_touch_down(touch)

class MyApp(App):
    def build(self):

        return Builder.load_string(kv)

if __name__ == '__main__':
    MyApp().run()
