GENIVI IVI layer management queries

We have queries regarding GENIVI layer management (IVI Application, IVI Controller)

1)      We are unable to select the opacity values of layer using this API ilm_layerSetOpacity between multiple layers, when changed the values from 0, 0.5 or 1 between multiple layers, we could not observe the transparency settings in the display

2)      If we have multiple wayland clients (Each creating a Surface) and a layer manager application (Maps every surface to an independent layer).  the first launched wayland clients get stalled once the new wayland client (eg: simple-shm.c with IVI surface) applications are launched. Only the latest  wayland application launched gets executed. However, if multiple surfaces are attached to a single layer, the client application works OK.

3)      How can the composition be achieved in multiple layers (using buffer's alpha value only or Surface/Layer Opacity also is effective)?.

4)      We are unable to select between multiple LCD's. This API(ilm_getPropertiesOfScreen()) is OK and returning proper details of screen, but this API[ilm_displaySetRenderOrder()] is unable to select between LCD with the provided display ID, how to choose a specific LCD to display Output.
