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".

Example with gradient

Gradients have a similar problem. The gradient is applied only to the first half of the surface. The second half is filled with the end color.
