<p class="MsoNormal">We are observing the following issue on Weston 10.0.2:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When we launch Weston with drm-backend and pixman renderer, we are seeing blank screen. Upon doing hotplug, display is coming up.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In layer dumps, we can see that a fully opaque layer is getting created during issue case as shown below:<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;margin-bottom:6.0pt">It is caused due to creation of fade layer in desktop-shell. Once the desktop-shell client is ready, the layer should fade in. But we suspect that the layer is not getting faded in properly.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;margin-bottom:6.0pt">To confirm, we made the following change to disable the creation of fade layer. With this change, the issue is getting resolved and Weston UI is up everytime.<o:p></o:p></p>
