Video output display plugin close event not working

I'm writing a video output out-of-tree plugin for VLC, and I notice that the close event that can be sent by the plugin module by calling :

vout_display_SendEventClose(vout_display_t *vd)

has no effect, or at least I didn't notice one or understand what it should do. I guess it is either suppose to close the plugin, or exit VLC.

By searching similar issue, I found the bug https://trac.videolan.org/vlc/ticket/11500 which is a bit related.

I also launched VLC with the vout plugin caca:

cvlc -vvv myVideoURL --vout=caca

and tried to exit it by clicking the Rex Cross button which trigger the event:

main vout display debug: VoutDisplayEvent 'close'

and nothing happen.

Thank you for your help
