[Linux] onWindowMove called on window focus and windowManager.getPosition() seems working bad

[acorn371]

Hi,
I'm developing app size/position size&position persistence by shared_preference on windows and linux platforms . On windows platform all work great.
On linux I'm having some issues:

1. WindowListener.onWindowMove and WindowListener.onWindowMoved are called on app window focus and aren't called on window move:

    @override
    void onWindowMove() {
      _platform.savePosition();
    }

    @override
    void onWindowMoved() {
      _platform.savePosition();
    }

2. inside method _platform.savePosition(); the call to final Offset pos = await windowManager.getPosition(); always return Offset(26.0, 23.0) moving and dragging my app window

    @override
    Future<void> savePosition() async  {
      final Offset pos = await windowManager.getPosition();
  
      await PlatformUtils.prefs.setDouble(PREF_MAINWIN_POSX, pos.dx);
      await PlatformUtils.prefs.setDouble(PREF_MAINWIN_POSY, pos.dy);
  
      print("save-pos: ${pos.dx} ${pos.dy}");
    }

I'm working with flutter 3.24.0 and window_manager: 0.4.2 on Debian 11.

Is there a workaround to these issues ? Or better, a patch ?
Thanks,
Marco

The same issue on Fedora Linux 39, GNOME Shell 45.10:

• onWindowMove() is called on focus event
• getBounds (and also getPosition) always return constant Offset(26.0, 23.0)
• setPosition has no effect
  The problem appears after upgrading to Fedora Linux 39 and newer GNOME version. On Fedora 38 everything worked fine.
  The problem is observed on all plugin versions (tested on 0.3.7 and the latest version).

Any ideas or workarounds how to fix the problem?
