Displacement, Tesseleation and RGBA Vertex Painting - Channels get inivisible on Color View.

Holla Folks,

i figured out, if you create a Shader with Displacement and Vertex Paint with it, it works fine, but the RGBA View,
gets invisible. Its not a big deal, i just wonder if its “normal”, if its a bug or something else.

i hope the graphic explains everything.
