WPF Margin在Windows XP / 7上的呈现方式不同

Question

我已经尝试过位于http://arbel.net/2006/11/03/forcing-wpf-to-use-a-specific-windows-theme/的hack但它对这个问题没有影响，这里可能涉及一些ScaleTransform，但它的值在两张图片中是相同的。 有没有人知道为什么会有这么大的差异，有没有办法解决它？

这是按钮的样式：

<Style x:Key="activityButtonStyle" TargetType="{x:Type Button}">
    <Setter Property="Margin" Value="0,3,0,3" />
    <Setter Property="Padding" Value="5" />
    <Setter Property="Foreground" Value="White" />
    <Setter Property="Background" Value="DarkGray" />
    <Setter Property="BorderThickness" Value="2" />
    <Setter Property="BorderBrush" Value="Black"/>
    <Setter Property="FontWeight" Value="Bold" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Grid>
