How can I avoid anti aliasing with WPF?

Question

One of the big problems with WPF is anti aliasing. In fact, that's why UseLayoutRending was introduced in WPF 4.0. However, it does not work for me in the following sample:

<StackPanel UseLayoutRounding="True" TextOptions.TextFormattingMode="Display" >
    <Line X1="0" Y1="0" X2="200" Y2="0" StrokeThickness="1" Stroke="Black" SnapsToDevicePixels="True" UseLayoutRounding="True"></Line>
    <Line X1="0" Y1="1.5" X2="200" Y2="1.5" StrokeThickness="1" Stroke="Black" SnapsToDevicePixels="True" UseLayoutRounding="True"></Line>
    <Line X1="0" Y1="3.5" X2="200" Y2="3.5" StrokeThickness="1" Stroke="Black" SnapsToDevicePixels="True" UseLayoutRounding="True"></Line>
    <Line X1="0" Y1="7" X2="200" Y2="7" StrokeThickness="1" Stroke="Black" SnapsToDevicePixels="True" UseLayoutRounding="True"></Line>
    <Line X1="0" Y1="9" X2="200" Y2="9" StrokeThickness="1" Stroke="Black" SnapsToDevicePixels="True" UseLayoutRounding="True"></Line>
</StackPanel>

The last two lines are still blurry. (I am using Windows 7)

Any solution?

Or is it a bug in the beta of WPF 4.0?

Have you tried to change the TextOptions.TextFormattingMode property to Display ? See this post from Lester Lobo for details
