WPF视图框鼠标指针隐藏在控件下

Question

我正在使用DataPiker控件中的Viewbox样式来增加日历的大小

    <DatePicker Name="DatePickerWaybillDate" 
                                   CalendarStyle="{StaticResource styleCalendar}"
                                   Grid.Column="1" 
                                   FontSize="25"
                                   VerticalContentAlignment="Center" 
                                   HorizontalContentAlignment="Center"                                   
                                   SelectedDateFormat="Short"
                                   SelectedDate="{Binding dWaybillDateInput, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" FirstDayOfWeek="Monday" Cursor="None" Padding="2" RenderTransformOrigin="0,0" ScrollViewer.CanContentScroll="True"
                                 >
                                <DatePicker.Resources>
                                    <Style TargetType="{x:Type DatePickerTextBox}">
                                        <Setter Property="IsEnabled" Value="False"/>
                                    </Style>
                                </DatePicker.Resources>
                            </DatePicker>


<Style x:Key="styleCalendar" TargetType="{x:Type Calendar}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Calendar}">
                        <!-- Wrapping in ViewBox will enlarge calendar of that size.-->
                        <Viewbox Height="400"
                                    Width="400">
                            <CalendarItem x:Name="PART_CalendarItem"
                              Background="{TemplateBinding Background}"
                              BorderBrush="{TemplateBinding BorderBrush}"
                              BorderThickness="{TemplateBinding BorderThickness}"/>
                        </Viewbox>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

但是当我运行应用程序时，将鼠标移至数据选择器时，鼠标指针将变为不可见。问题是当我在PC上运行应用程序时看起来不错，但是当我将应用程序迁移到服务器时出现了问题
