Nicolai, <br><br>I tried the application using (I assume that is what you meant):<br><span style=" color:#800080;">QApplication</span><span style=" color:#000000;">::</span>setGraphicsSystem<span style=" color:#000000;">(</span><span style=" color:#008000;">"opengl"</span><span style=" color:#000000;">);<br>
<br>and haven't been able to crash the application but it gets really slow and unresponsive. Also I get these error messages on my log:<br></span><span style=" color:#008000;"></span><br><span style=" font-family:'Courier'; font-size:10pt; color:#aa0000;">Valid eglHandle received but not running with meego compatible graphicssystem.<br>

Have you tried to use a QGLWidget for the qmlviewer ?<br>This works for the QML Camera element which has the <br>same behavior, segfaults when application moved to background.<div><div></div><div class="h5"><br><br><div class="gmail_quote">
