Hi, anyone wanna look over this OpenGL context initialization code and see if there's anything wrong with it?

#

here's output.bmp when bool useGLFWContext = true;

#

#

#

as is apparent, the triangle isn't visible when I initialize OpenGL with EGL to use a DRM render node

#

but it is visible when I initialize OpenGL with GLFW
