You don't always need to clear the depth buffer, but I do anyway so i don't forget.

Code:

'$include: 'gl/gl.bi'
'$include: 'gl/glu.bi'
'$include: 'gl/glfw.bi'

if glfwInit <> GL_TRUE then
    print "could not init"
    end 1
end if


if glfwOpenWindow(640, 480, 8, 8, 8, 8, 24, 8, GLFW_Fullscreen) <> GL_TRUE then
    print "could not open window"
    glfwTerminate
    end 1
end if

glViewport 0, 0, 640, 480


do
    glClear GL_COLOR_BUFFER_BIT OR GL_DEPTH_BUFFER_BIT
    
    
    glBegin GL_LINES
        glVertex2f 0,0
        glVertex2f 1,1
    glEnd
    
    glFlush
    
    glfwSwapBuffers
        
    if glfwGetKey(GLFW_KEY_ESC) or glfwGetWindowParam(GLFW_OPENED) = 0 then exit do
    
loop


glfwTerminate
