Hello Kristian, I'm don't using mesa, we have a Vivante driver stack on imx6 which also uses a proprietary wayland protocol to send a buffer to the compositor and it's EGL implementation don't creates a separate event queue it uses the main wayland display queue and will call wl_display_dispatch function. But thanks for the hint, i suppose the current mesa implementation should answer all my questions above.
