What you see is not the svi background, but the shadow, which is part of the default template. If you want to get rid of the shadow, you need to redefine the control template.
So like this:
<s:ScatterView> <s:ScatterViewItem Background="Transparent"> <s:ScatterViewItem.Template> <ControlTemplate> <TextBlock>Hello World</TextBlock> </ControlTemplate> </s:ScatterViewItem.Template> </s:ScatterViewItem> </s:ScatterView>
Keep in mind that if you replace it this way, you will lose all other small visual flashes, such as the pick up effect and flicker. If you want to save them, just use blend to edit a copy of the existing template and remove the shadow.
