<p class="MsoNormal"><span style="font-size:12.0pt">Hi Weston team,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">We are working on Weston 10 version. We have a use case where we are playing a video using Gstreamer and on top of it we are running a Weston-simple-egl app.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">Status bar and the Weston-simple-egl layer is sent to gl-renderer for GPU composition and Video is sent to Display processing unit.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">So finally gl-renderer’s output is composed with the Video layer in Display processing unit. But we see that there is corruption in this use case.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">The output of gl-renderer is having some garbage data. We dumped the output of gl-renderer onto a RAW file and when we open it on a image editor we see same corruption in the gl-renderer’s output.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">When we force all the layers (simple-egl + Video + Status bar) to go to GPU composition there is no issue.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">When we run only Video there is no problem. When we run only Weston-simple-egl then also there is no problem. But when we run simple-egl app on top of Video we see this corruption.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">Any pointers to debug or fix this issue will be really helpful.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">Below is the corruption<o:p></o:p></span></p>
