Description
couldn't use OpenGL 3.3 via QOpenGLFunctions_3_3_core,
even if you new a pointer of QOpenGLFunctions_3_3_core, and initialisze,
when you use glcreateshader via QOpenGLFunctions_3_3_core, the program crashes
Above code is another example, which indicates Qt may only use OpenGL 2.1 in MacOS big sur,
which is impossible.
QSurfaceFormat format;
format.setVersion(3,3);
format.setProfile(QSurfaceFormat::CoreProfile);
QOpenGLContext::currentContext()->setFormat(format);
will fail.After these line of code
QOpenGLContext::currentContext()->format().version is still 2 1 which is astonishing
QOpenGL seems not to work well in Big sur.
QOpenGLContext::currentContext()->versionFunctions<QOpenGLFunctions_3_3_Core>() is nullptr
