还原后 C# WPF 窗口未正确显示

Question

我有一个非常通用的 WPF 窗口，它开始最大化。当这个窗口最小化到任务栏，然后恢复窗口不再填满屏幕。它在右侧显示了桌面的一小部分。 Windows 仍然认为它已最大化，当设置为正常然后再次最大化时，它看起来应该是这样，直到再次最小化。

    public partial class MainWindow : Window
{

    public MainWindow()
    {
        InitializeComponent();
        this.MaxHeight = SystemParameters.MaximizedPrimaryScreenHeight;
        this.MaxWidth = SystemParameters.MaximizedPrimaryScreenWidth;
    }

    private void ExitBtn_Click(object sender, MouseButtonEventArgs e)
    {
        this.Close();
    }
    private void MaxBtn_Click(object sender, MouseButtonEventArgs e)
    {
        this.WindowState = WindowState.Maximized;
        //Application.Current.MainWindow.WindowState = WindowState.Maximized;
        resizeBtn.Visibility = Visibility.Visible;
        maximizeBtn.Visibility = Visibility.Hidden;
    }
    private void ResBtn_Click(object sender, MouseButtonEventArgs e)
    {
        this.WindowState = WindowState.Normal;
        resizeBtn.Visibility = Visibility.Hidden;
        maximizeBtn.Visibility = Visibility.Visible;
    }
    private void MinBtn_Click(object sender, MouseButtonEventArgs e)
    {
        this.WindowState = WindowState.Minimized;
    }
    private void TitleBar_DblClick(object sender, MouseButtonEventArgs e)
    {
        if (this.WindowState == WindowState.Normal){ this.WindowState = WindowState.Maximized; return; }
        if (this.WindowState == WindowState.Maximized) { this.WindowState = WindowState.Normal; return; }
    }
}

你的想法？ 更新：

似乎与 can resize 属性有关。如果我将它设置为 ca 最小化就可以了。使用夹子调整大小或可以调整大小导致窗口在最小化到任务栏后改变大小。

回答：问题仅与我的显示器有关。还没有弄清楚，但该程序在另一台 PC 上按预期运行。非常感谢@Vanna 帮助我解析了这一点。
