<br>note that you can already try the first solution I suggested in the last mail:<br><br>Use glfilterapp (see the link I past in last mail), then in the drawcallback you have to call src = glGetCurrentContext(), then glCopyContext(src, dst, ...), just one time.<br>
<br>You can also use dst = glGetCurrentContext() in your gl framework thread, to get the gestination.<br><br>Let me know if it works.<br><br>Julien<br><br>
