Window drag and caption buttons do not work when custom title bar is applied

[ojh050118]

Describe the bug

I applied a custom title bar, but the dragging and caption buttons do not work. Occurs with package versions 1.2.230313.1 and 1.3.230331000.

Steps to reproduce the bug

xaml:

<Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="32"/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <Grid x:Name="AppTitleBar" Grid.Row="0">
            <Image x:Name="TitleBarIcon" Source="/Images/finder.png"
                   HorizontalAlignment="Left"
                   Width="16" Height="16"
                   Margin="8,0,0,0"/>
            <TextBlock x:Name="TitleTextBlock"
                Text="{x:Bind Title}"
                Style="{StaticResource CaptionTextBlockStyle}"
                VerticalAlignment="Center"
                Margin="28,0,0,0"/>
        </Grid>
        <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center" Spacing="10" Grid.Row="1">
            <Button x:Name="myButton" Click="myButton_Click">Click Me</Button>
            <TextBox Name="TextBox" PlaceholderText="Text me" MinWidth="200"></TextBox>
        </StackPanel>
    </Grid>

CSharp:

public MainWindow()
{
    InitializeComponent();

    SystemBackdrop = new MicaBackdrop();
    Title = TitleTextBlock.Text = "Remote Audio";
    ExtendsContentIntoTitleBar = true;
    SetTitleBar(AppTitleBar);
}

Expected behavior

Window dragging and caption buttons all work.

I found one issue that seems to be related to this.
Resizing the window by dragging the border of the window didn't work. The shape of the mouse did not change to a "Vertical Scaling" shape.

This issue was resolved by recreating the project with the "Blank App, Packaged" project template instead of "Blank App, Package with Windows Application Packaging Project".
I'll keep this thread open though.

I have the same issue on my application running on visual studio:

Not sure when this started happening. Microsoft store version with winappsdk updated separately don't show this problem.
Switching to WinAppSDK method from WinUI3 for customizing titlebar fixed the issue for me in visual studio.

Thanks for posting this. We are currently in process of improving this experience. Meanwhile, I can suggest some workaround if possible. @ojh050118 does it still occur with latest release of WinAppSDK (1.3.1) ?

It has been fixed and now works fine.
