[M0n7y5]

Hi,
i found weird visual artifacts in Demo app, section Navigation Rail. You can see whats happening on gif bellow:

Thanks for reporting this. This was a known bug at time of release. It is actually related to the ripple control, not the Navigation Rail. Since this was a pre-existing problem and not caused by the navigation rail, I elected to release it as is, and plan to circle back on this one.

Looks like its the AdornerDecorator for the ShadowEdge in the CardTemplate that causes the issue. It happens only when the TabControl has a ShadowDepth set. Maybe this information can help someone else continue debugging.

By the moment, It's better to work with materialDesign:ShadowAssist.ShadowDepth="Depth0" on TabControl instance.

We have the same issue in our application.

More over it looks similiar to the blurry text menu issue we've been experiencing too. Maybe we can try a similar hack?

@stigrune Indeed the ArdornerDecorator was provoking the issue, I'm not sure why it's needed there I kept the border with the edge and it still looks good.
