Thanks!

Could you provide a sample app to reproduce the issue too?

import flet as ft


def main(page: ft.Page):
    page.add(ft.SafeArea(ft.Text("Hello, Flet!")))


ft.app(main,view=ft.AppView.FLET_APP_HIDDEN)

This example doesn't work on macOS as well:

from time import sleep

import flet as ft


def main(page: ft.Page):

    page.add(
        ft.Text("Hello!")
    )

    sleep(3)
    page.window_visible = True
    page.update()  

ft.app(target=main, view=ft.AppView.FLET_APP_HIDDEN)

Looks like a bug.
