That was my initial thought too, but in order to create the context to check the results, I need an application. But if I set the default after I create the application I get a warning:Warning: Setting a new default format with a different version or profile after the global shared context is created may cause issues with context sharing. (qsurfaceformat.cpp:836, static void QSurfaceFormat::setDefaultFormat(const QSurfaceFormat &))(Which is what it says in the docs for QSurfaceFormat::setDefaultFormat()) Hence the catch-22.
Are you destroying the QGuiApplication object after an unsuccessful test, and recreating it after changing the default format?
