title: Can OpenGL render two Qt panels together?
body: <p>I have a Qt application, the main window has two panels, one is a customized <code>QWidget</code> which uses <em>OpenGL</em> to draw the content, and the other is a <code>QWebEngineView</code> which I newly added. My problem is when this <code>QWebEngineView</code> loads Url, the other <code>QWidget</code> won't show the content. </p>
  
  <p>I searched that <code>QWebEngineView</code> also uses <em>OpenGL</em> to render the web page, I'm wondering whether it's because of some conflicts of <em>OpenGL</em>. Can't <em>OpenGL</em> render two panels together? If so, is there any way to solve this? For the customized <code>QWidget</code>, it has to use <em>OpenGL</em>, so is there any workaround I can do for the <code>QWebEngineView</code>? </p>
