<p class="MsoNormal" style="margin-bottom:12.0pt">We are facing issue when we are trying to add same surface to multiple layers. When we try to attach surface to another layer, it is getting detached from the earlier layer.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">We are using wayland/weston/wayland-ivi-extension 1.11.0 with drm-backend on TI's Soc.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Could anyone know if this is the limitation of ILM 1.11.0 ? Is this fixed in newer version and can it be ported to 1.11.0 ? or Is there any other way to show same surface on multiple layers?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I see it was the limitation with wayland-ivi-extesnion 1.9.0 as below [1].
<o:p></o:p></p>
<pre><i>"Currently 1 layer can be only on 1 screen, and 1 surface can be only on 1 layer,<br> we are planning to relax this limitation And allow 1 surface to be on many layers but we would need to break the ABI and change the <br>ivi-controller protocol."</i><o:p></o:p></pre>
