C＃WPF窗口恢复后没有正确显示

Question

我有一个非常通用的WPF窗口开始最大化。当这个窗口最小化到任务栏，然后恢复窗口不再填充屏幕。它显示了右侧桌面的一小部分。 Windows仍然认为它是最大化的，当设置为正常，然后再次最大化时，它看起来应该再次最小化。

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; } 
    } 
} 

您的想法？ 更新：

似乎与可调整大小的财产。如果我将其设置为可以最小化，那很好。使用手柄调整大小或调整大小可使窗口在最小化为任务栏后更改大小。

答：问题是什么，只有我的显示器。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帮我解析了这一点。
