OpenGL:glBitmap depth cannot disable.

When we use glDepthRange(0.0, 0.0), depth of 1st glBitmap function cannot disable with a Radeon R7 250. Depth of 2nd glBitmap function is disable. I would like to know how to disable 1st  glBitmap too.

glDepthFunc(GL_LEQUAL);

glEnable(GL_DEPTH_TEST);

glDepthMask(GL_TRUE);

glPixelStoref(GL_UNPACK_ALIGNMENT, 1);

glRasterPos3fv(vec);

// Draw Bitmap (1st)

glDepthRange(0.0, 0.0);

glPixelStoref(GL_UNPACK_ALIGNMENT, 1);

glRasterPos3fv(vec);

glBitmap(16, 16, 8.0f, 8.0f, 10.0f, 0.0f, bitmapCircle16);

glDepthRange(0.0, 1.0);

// Draw Bitmap (2nd)

glDepthRange(0.0, 0.0);

glBitmap(16, 16, 8.0f, 8.0f, 10.0f, 0.0f, bitmapCircle16);

glDepthRange(0.0, 1.0);
