      I try to make QOpenGLWidget use OpenGL ES 3.1 using ANGLE. The problem is that during creation of QWindowsEGLContext such attribute is set:

       

      contextAttrs.append(EGL_CONTEXT_CLIENT_VERSION);
 contextAttrs.append(m_format.majorVersion());
 contextAttrs.append(EGL_NONE);

       

      As a result, opengl version is set to 3.0 (if values is missing (minor version) it is set to 0). 

      I have fixed it with code:

      contextAttrs.append(EGL_CONTEXT_MAJOR_VERSION);
 contextAttrs.append(m_format.majorVersion());
 contextAttrs.append(EGL_CONTEXT_MINOR_VERSION);
 contextAttrs.append(m_format.minorVersion());
 contextAttrs.append(EGL_NONE);

      Is it possible to add this fix to Qt?
