Gridview scrolling stutters - xaml

Question

I've been experimenting with Windows 8 and Visual Studio 2012 express but I can't achieve my goal.
I've been trying to create a grid of tiles that expands horizontally (much like the 'start' screen does).
The items are added at runtime and although scrolling horizontally works, it's not good enough.
When using my touchpad, it seems to clip to something, on a tablet this would feel laggy.
Scrolling with the cursor seems fine.
I'd like to know how I can give it a smooth experience by using XAML, unfortunately I'm not very good at it (yet).
XAML: (the stackpanel should be pointless but I was experimenting)
<Grid Background="White" ScrollViewer.HorizontalScrollBarVisibility="Visible">
<Grid.RowDefinitions>
<RowDefinition Height="19*"/>
<RowDefinition Height="109*"/>
</Grid.RowDefinitions>
<StackPanel x:Name="stackPanel1" HorizontalAlignment="Left" Height="622" Margin="97,93,0,0" VerticalAlignment="Top" Width="0" Orientation="Horizontal" Grid.RowSpan="2"/>
<GridView x:Name="gridView1" ItemTemplate="{StaticResource Standard250x250ItemTemplate}" Margin="0,0,0,0" Background="Red" Grid.Row="1" ScrollViewer.HorizontalScrollBarVisibility="Hidden"/>
<Image HorizontalAlignment="Left" Height="90" Margin="1206,11,0,0" VerticalAlignment="Top" Width="106" Source="Assets/SmallLogo.png"/>
</Grid>

Not 100% sure if this is the issue you're facing though, but maybe it helps:
By default the ItemsTemplatePanel of a GridView is a VirtualizingStackPanel. If you don't have many items in your GridView, the scrolling of your GridView can indeed seem to be stuttering.
Try setting the ItemsPanelTemplate to a StackPanel in stead of VirtualizingStackPanel (unless you insist that your control GridView virtualizes its items).
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Width="Auto"
HorizontalAlignment="Left"
Orientation="Horizontal" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
Hope this helps!
