    Description

      According to one of my user's feedback, the software I developed by QQuickFramebufferObject which calls the QOpenGLExtraFunctions cannot run on the Intel graph hd3000 graphics card. Through the dump file provided by him, I traced that the software had triggered an illegal access in the place of QOpenGLExtraFunctions::glGenVertexArrays, and there is absolutely no problem on most other users' machine.

      I noticed that some people in the internet talking about the lib GLEW crash in glGenVertexArrays as well, They solved the problem by adding the code glewExperimental = GL_TRUE;

      So my question is whether the problem of QOpenGLExtraFunctions is similar to that of GLEW , and whether there is a magic switch in QOpenGLExtraFunctions just like glewExperimental = GL_TRUE.

      Best regards.
