            Bug ID: 131569
           Summary: Stretched bitmap fill covers only half of the lateral
                    surfaces of an 3D-extrusion object

          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal

Examples

Open attached document for to follow the steps.
Draw a closed polygon and fill it with a bitmap. Set the fill style to
"Stretched".
Convert the shape to a 3D-Lathe object. That is in context menu -> Convert ->
"To 3D".
Set the line style of the object to solid. That way you will be able to see
empty surfaces.
Open the "3D Effects" dialog. That can be done from context menu.
Set the "Corner Radius" and "Scaled Depth" to 0%. That reduces the front face
of the prism so that you can see the lateral surfaces.
Go to tab "Textures" in the "3D Effects" dialog. Set the texture kinds
"Projection X" and "Projection Y" to "Object Specific". That is the left
button.
Notice, that only the half of the lateral surfaces is filled, although
"stretched" means to fill the entire area.

I consider this a bug, because all other kind of fillings will fill the entire
area. For example set the area fill style to "Tiled". Or change the fill from
"Bitmap" to "Gradient".
