Unity5 Beta18: UI Image has problems with Materials (and Source Images) -> looks strange

Hi,

today I imported a UI from Unity3D 4.6 (worked fine) to Unity3D 5 Beta18 (looks strange).

I created a material with the UI/Lit/Bumped shader (other shades also didn't work) and put a diffuse texture in it (Texture! not Sprite) , Canvas set to Screen Space -Camera with following setups:

Panel:

Material:

The game view shows no texture ! (in Unity4.6 the texture will be shown).

It's getting more strange if together with the material a Sprite is used for the source image:

It worked in Unity3D 4.6.

(In general I don't understand why I can put two images on the plane -one source image and another one in the material - but that's a different question.)

Here's a package with a test scene which shows the error.

Thanks for your assistance and best regards,

Here the three images:

Panel setup -> Game view shows no image on plane! :


Material setup -> Game view shows no image on plane! :


Material + Source Image = Strange effect on texture:
