Wayland backend doesn't handle WL_EVENT_WRITABLE
wl_event_loop_add_fd
is not called with WL_EVENT_WRITABLE
:
https://gitlab.freedesktop.org/wayland/weston/blob/master/libweston/compositor-wayland.c#L2789
However this is handled in wayland_backend_handle_event
:
https://gitlab.freedesktop.org/wayland/weston/blob/master/libweston/compositor-wayland.c#L2605
Should we add WL_EVENT_WRITABLE
to wl_event_loop_add_fd
?
