If you look at the code more closely you'll see that EGL_CONTEXT_CLIENT_VERSION is set regardless of the API and presence of KHR_create_context. Both of which rather important :) With that said, I'll repeat my request - please flesh out a simple test app (which does not depend on QT), before we jump on the pointing fingers train :-P</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
