You could check if the ImageButton
control from WinRT XAML Toolkit is a better solution for you. Currently your template is all wrong since you are replacing it with another Button
that is using a default template. You can extract the default template by right clicking your button in the design view - either in Blend or VS, or in the Document Outline panel. This is the default template:

You can remove the Storyboards
from the "PointerOver" and "Pressed" states in the VSM and you should get the desired effects.
