Transparent window background on linux

[Kawue]

I tried to make the background of my window transparent using the example code given in the documentation. However, on linux mint I get a black background instead of a transparent one. Is there a workaround to get transparency on linux?

Operating system: Linux Mint
Flet Version: 0.7.4

import flet as ft

def main(page: ft.Page):
    page.window_bgcolor = ft.colors.TRANSPARENT
    page.bgcolor = ft.colors.TRANSPARENT
    page.window_title_bar_hidden = True
    page.window_frameless = True
    page.window_left = 400
    page.window_top = 200
    page.add(ft.ElevatedButton("I'm a floating button!"))

ft.app(target=main)

I also am having this problem in Arch Linux with flet version 0.17.0

The window_manager dart package used by Flet has an opened issue for this: leanflutter/window_manager#179

I see where exactly in the Flet source code I can comment out those two lines, but I am unsure how to use that change in my flet app.

Which lines do you mean?

i think in the linked issue there was a workaround commented, though idk how to modify the flet source myself
