It seems to me that your driver is doing things it isn't
actually supposed to do. This code is binding a vertex buffer
object with a function which is supposed to bind a vertex array
object. The only reason the vbo is bound at all is because of
the call to glBindBuffer in the misnamed initVAO -- a function
which never even initializes a vao. The spec actually requires
a vao to be created and a shader program to be bound, so I
would expect a conforming driver to show nothing.
I expect a couple of calls to glError will not come up empty.
Right, the triangle is well drawn but glGetError returns 1282.
Maybe the OP has a different OGL implementation. At least NVidia
driver renders a triangle for this code.
