Window-system: EGL/GLX/WGL Underlying platform: X/Wayland/Android/etc, when EGL is used Agreed, they are window-system objects. Although I cannot see any reason why we'd need a pixmap here (EGL). In the GLX case, it's required due to server-side rendering. One needs a separate primitive for each pbuffer, thus the information can be passed long the wire. Feel free to share links which might shed some light.
