This is a confirmed issue when the video player is fullscreen and back to original size, or if you make it fullscreen from original size.
The main window of windows looks like this.
Is there any way to solve it?
When switching from full-screen mode to the previous mode or from the previous mode to full-screen mode, the blue main window is visible.
Is it possible to make the blue main window completely transparent?
A light blue border is visible in the process of quickly switching between full screen and full screen.

    I'm a little confused.
    So the issue is that the "blue window border" shouldn't be visible, right ?
    You want a "borderless-window" when switching back to original size, right ?

    I wanna to know is there a "blue window border" when you creating a NEW flutter project without any code change ?

    you can try:

    `
    if (fullscreen) {
    .....
    } else {
    if (!g_saved_window_info.maximized) SendMessage(hwnd, WM_SYSCOMMAND, SC_RESTORE, 0);

       /// change this line. 
        SetWindowLong(hwnd, GWL_STYLE, g_saved_window_info.style & ~(WS_CAPTION | WS_THICKFRAME));
      ......
    }
    

    `
