ClientSizeProperty.Changed.Subscribe(size =>
{
    var x = (size.OldValue.Value.Width - size.NewValue.Value.Width) / 2 * Scaling;
    var y = (size.OldValue.Value.Height - size.NewValue.Value.Height) / 2 * Scaling;

    Position = new PixelPoint(Position.X + (int)x, Position.Y + (int)y);
});

public double Scaling => Screens.ScreenFromWindow(this)!.Scaling;

I need to multiply x and y by window scaling factor. Otherwise, the window would slowly shift.

Is this the right way to fix?
