Windows can't remember thier old position

[Shadowblitz16]

I have been messing with this for a while to try to get the tool window to remember it's old location, I tried several events like OnActivate, OnClosing, OnLocationChanged, and OnVisabilityChanged.

Sadly even with StartPosition set to manual the window can't be set to remember it's old position.

using System;
using SMBXR.Engine;
using Alternet.UI;
using Alternet.Drawing;

namespace SMBXR;

public partial class LevelSettingsView : Window 
{
    public MainView? MainView { get; set; }
    public PointD   LastLocation { get; private set; }
    public LevelSettingsView()
    {
        IsToolWindow  = true;
        CloseEnabled  = false;
        StartLocation = WindowStartLocation.Manual;
        InitializeComponent();
    }

    private void OnSectionBoundsEdit(object sender, EventArgs args)
    {
        if (MainView == null) return;
        MainView.ResizeMode = SectionResizeMode.Edit;
    }

    private void OnSectionBoundsTop(object sender, EventArgs args)
    {
        if (MainView == null) return;
        MainView.ResizeMode = SectionResizeMode.Top;
    }

    private void OnSectionBoundsLeft(object sender, EventArgs args)
    {
        if (MainView == null) return;
        MainView.ResizeMode = SectionResizeMode.Left;
    }
    private void OnSectionBoundsRight(object sender, EventArgs args)
    {
        if (MainView == null) return;
        MainView.ResizeMode = SectionResizeMode.Right;
    }
    private void OnSectionBoundsBottom(object sender, EventArgs args)
    {
        if (MainView == null) return;
        MainView.ResizeMode = SectionResizeMode.Bottom;
    }

    protected override void OnLocationChanged(EventArgs e)
    {
        base.OnLocationChanged(e);
        if (Location == PointD.Empty) return;
        LastLocation = Location;
        Console.WriteLine("Moved To: "+LastLocation);
    }

    protected override void OnVisibleChanged(EventArgs e)
    {
        base.OnVisibleChanged(e);
        if (LastLocation == PointD.Empty) return;
        Location = LastLocation;
        Console.WriteLine("Reset To: "+Location);
    }
}

Is this happens on Linux? If so, Window.Location is not possible to set on some Linux versions. For example, it happens on Ubuntu 23. This is due to new restrictions in Linux window manager and is not related to Alternet.UI. Currently I can suggest do not have separate windows in the applications if their locations are critical to the user interface. We cannot control window positions on Linux.

that's too bad.
