Bad rendering on MacOS/Catalyst with a Uno Platform project

[ArchieCoder]

Describe the bug
The first different is the black background. I would have expected white like Windows or Linux. The bug is the rendering is not working as expected when Catalyst output is used. It works with MacOS/Skia. See screenshot below:

To Reproduce
1- Create a new Uno Project using the latest version (Single Project).

2- Add the control

<winUi:CartesianChart
Grid.Row="2"
Series="{Binding Series}"
XAxes="{Binding XAxes}"
YAxes="{Binding YAxes}" />

3- Create the data

public ISeries[] Series { get; set; } =
{
new LineSeries
{
Values = new ObservableCollection
{
new DateTimePoint(new DateTime(2021, 1, 1), 300),
new DateTimePoint(new DateTime(2021, 2, 1), 600),
new DateTimePoint(new DateTime(2021, 3, 1), 500),
new DateTimePoint(new DateTime(2021, 4, 1), 300),
new DateTimePoint(new DateTime(2021, 5, 1), 500),
new DateTimePoint(new DateTime(2021, 6, 1), 600),
new DateTimePoint(new DateTime(2021, 7, 1), 800),
new DateTimePoint(new DateTime(2021, 8, 1), 700),
new DateTimePoint(new DateTime(2021, 9, 1), 900),
new DateTimePoint(new DateTime(2021, 10, 1), 600),
new DateTimePoint(new DateTime(2021, 11, 1), 800),
new DateTimePoint(new DateTime(2021, 12, 1), 750)
}
}
};

public Axis[] XAxes { get; set; } =
{
new DateTimeAxis(TimeSpan.FromDays(1), date => date.ToString("MMM dd"))
};

public Axis[] YAxes { get; set; } =
{
new Axis
{
Name = "kW",
TextSize = 20,
}
};

Expected behavior
This should be like Windows or Linux output:
