      Qt Quick 3D - 49/50

      Description

      When a node with material having partially transparent Qt Quick content as a texture is added to View3D scene it is first drawn with transparent parts grey. Node with fully transparent Qt Quick content is drawn fully grey, see fully_transparent_cylinder.png. When a next node is added dynamically to the scene transparent areas change from grey to transparent. Also, moving mouse outside View3D and back may cause re-draw which gets rid of the grey color.

      Test application attached.
