Call QCoreApplication::setAttribute(Qt::AA_UseOpenGLES) before anything else, most importantly before constructing the Q(Gui)Application.
Right now you are making your request way too late, after WebEngine (and potentially others) have already run OpenGL related code.

This means that when we ask Qt which OpenGL module is in use it returns LibGL. The method we use to get the use-gl flag is QOpenGLContext::openGLModuleType which in turn asks QWindowsIntegration::openGLModuleType which does not check the application flags. You better open a bug report on it. `Allan _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
