> Description:
>
> When trying to use a second material or more on an object, the faces where it is applied become transparent or in some cases they are distorted as black rectangles that stretch to the origin (this second occurs above all with more complex models than a cube). This bug is noticed in edit mode or object, obviously if in viewport shading the option of material color or texture is used. In the other color modes of the Viewport Shading as Object, Vertex, Single or Random, the meshes of the object are displayed without the errors mentioned above.** It happens in Blender 2.81 as well as in Blender 2.82, but in Blender 2.80 there is no such error.**
