ps: i had a chat with a mozilla developer some time ago: they never use desktop opengl on windows, but only use ANGLE with a fallback to software rendering, if the application crashes on customer's machines.
You can force Qt to use Angle by setting the QT_OPENGL environment variable to QT_OPENGL=angle. Then detect if it crashes, by registering a signal handler or similar (sorry, Qt cannot do that for you). If it has crashed the last time set QT_OPENGL=software. There you have the same behavior.
