[Interest] Still getting crashes inside of Intel OpenGL drivers even after setting QT_OPENGL=software

[Jean-Michaël Celerier]

A good first step would be to put a breakpoint on LoadLibrary /
LoadLibraryEx to see who ends up loading that library:
maybe there's some raw opengl call somewhere that ends up loading the GL
library dynamically anyways
(e.g. wglCreateContext may possibly do that ? GDI32::SwapBuffers and some
other GDI functions too if you're using that anywhere in your app for some
reason).

Kind regards,
Jean-Michaël
