Xbox UWP app: Pointer mode does not work properly when scaling is set to default (200 %)

[remokeitel]

Describe the bug

The UWP app is configured for the Xbox so that the pointer mode is only enabled when requested (RequiresPointerMode = ApplicationRequiresPointerMode.WhenRequested). The scaling is set to default (200 % for UWP apps). One page was created with a ScrollViewer and one with a WebView2 control. Both controls have the properties "RequiresPointer=WhenEngaged" and "IsFocusEngagementEnabled=True". As soon as the controls receive the focus and the pointer mode is activated (IsFocusEngaged = True), the pointer appears. However, the pointer can only be used in 25 % of the area of the control at the top left. As soon as scaling is disabled (ApplicationViewScaling.TrySetDisableLayoutScaling(true)) and the app is displayed at 100 %, the pointer can be navigated over the entire area of the control.

Steps to reproduce the bug

App.xaml.cs:

public App()
{
    this.InitializeComponent();
    this.Suspending += OnSuspending;

    if (AnalyticsInfo.VersionInfo.DeviceFamily == "Windows.Xbox")
    {
        this.RequiresPointerMode = ApplicationRequiresPointerMode.WhenRequested;
        //ApplicationViewScaling.TrySetDisableLayoutScaling(true);
    }
}

MainPage.xaml:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <TextBox Grid.Row="0" Text="Test" />
    <ScrollViewer
        x:Name="ScrollViewer"
        Grid.Row="1"
        IsFocusEngagementEnabled="True"
        RequiresPointer="WhenEngaged"
        GotFocus="ScrollViewer_GotFocus">
        <StackPanel>
            <TextBlock Text="Hello" />
        </StackPanel>
    </ScrollViewer>
</Grid>

MainPage.xaml.cs:

public MainPage()
{
    this.InitializeComponent();
}

private void ScrollViewer_GotFocus(object sender, RoutedEventArgs args)
{
    ScrollViewer.IsFocusEngaged = true;
}

Navigate to ScrollViewer with Xbox Controller, so that it gets the focus.

Expected behavior

Pointer can be navigated over the entire area of the control by default Xbox UWP scaling (200 %)

The WinUI team is currently spending its time on WinUI 3. To help with this focus, any new bug filed against WinUI 2 is closed in this repo unless it's a security issue or is critical to our business priorities.

@ranjeshj But on Xbox there is no WinUI 3 available! And this issue has nothing to do with WinUI, but with UWP (without WinUI).

Don't Ever Use WinUI3!

That's the message that this is telling: Eventually, they will abandon WinUI3 in the same way like they do for WinUI2 - from one day to another.

Anyway, it seems like WinUI3 has been abandoned already and whether:

• Your issue remains open and ignored (WinUI3), or
• Your issue is closed and ignored (WinUI2)

doesn't make a difference at all.
