Description
Hello, I have built and run the current sources in /video/opengl/libretro_test_gl_fixedfunction in 3 different machines (Windows 7, Windows 10 and MacOS 10.14). In all 3 cases the core shows a flat color window, but the rectangle that should be drawn does not appear.
I have tried several variations for vertex coordinates and matrices, but no geometry is ever drawn. The background color does show, which suggests that the screen clear and the copy to framebuffer are indeed working. I also verified that the core is running in a compatibility context, and no GL_INVALID_OPERATION happens with glBegin(), etc. Any clue what could be happening here?

Research direction
Start by building and running /video/opengl/libretro_test_gl_fixedfunction on a compatibility-context OpenGL setup, then inspect the sample's rendering path around the clear, geometry draw, and framebuffer copy. Done means the expected rectangle appears instead of only a flat-color window.
