C# WPF文本在cleartype和非cleartype之间闪烁

我对WPF有问题。。。这有点奇怪

我最近迁移到使用MahApps.Metro作为我的窗口，当我在我的登录屏幕上时，它每隔几秒钟就会在cleartype和非cleartype之间闪烁

这是我的XAML文件

MainWindow.xaml

<Controls:MetroWindow x:Class="LegendaryClient.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
        Title="LegendaryClient" Height="600" Width="1024" MinHeight="600" MinWidth="1024"
        ShowIconOnTitleBar="True" SaveWindowPosition="True" Icon="Icon.ico" ResizeMode="CanResizeWithGrip" TitleCaps="False">

    <Controls:MetroWindow.WindowCommands>
        <Controls:WindowCommands>
            <Button Content="settings" />
            <Button x:Name="ThemeButton" Click="ThemeButton_Click" Content="theme"/>
        </Controls:WindowCommands>
    </Controls:MetroWindow.WindowCommands>

    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colours.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
                <ResourceDictionary Source="Controls/Steel.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>

    <Grid>
        <ContentControl x:Name="Container" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/>
    </Grid>
</Controls:MetroWindow>

及

任何帮助都将不胜感激

谢谢

结果是由于某种原因，

导致我的文本闪烁。。。把它放在网格外，就不会模糊了
