<div>
<p class="MsoNormal">I see it was the limitation with wayland-ivi-extesnion 1.9.0 as below [1].

<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><u></u><u></u></pre>
