Second Window Freezing Issue

[Jack251970]

Describe the bug

If I open second window and hide the main window, the second window will freeze if I lock my laptop and login in.

Reproduction

1. Bind this function to MainWindow in Gallery project.

private void MainWindow_OnClosing(object? sender, CancelEventArgs e)
{
    Hide();
    e.Cancel = true;
}

2. Open Gallery main window.
3. Open second window from Dialog and Flyouts -> ContentDialog -> Open a new window.
4. Close Gallery main window. (It is hidden)
5. Sleep or lock system.
6. Logon in system.
7. Click Show content dialog in this window button. (No context dialog created. Try to drag and move the window which can possibly cause system black screen for a while. Then the dialog is created.)

Suggested Solution

It is related to CacheMode but I am not sure how much we need to change it.
