Hi I have problem, when I set up HorizontalGridLinesBrush to my grid, it gets blurred (when I set top margin to 32 everything is fine)

here is my caml grid row setup:

<ControlTemplate x:Key="GridViewRowTemplate" TargetType="grid:GridViewRow">
        <Border BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}">

Hi Jiri,


We have tried to replicate the behavior you described, however to no avail. Would it be possible to check the attached project and let us know how it differs from yours?
