So yes, https://patchwork.freedesktop.org/patch/217833/ prevents the crash.

I found skypeforlinux to be a excellent test for these issues, like moving
the pointer pover the toplevel menu bar while a menu is opened to map/unmap
the menus quickly would have led to a crash previously. Not anymore, with
https://patchwork.freedesktop.org/patch/217833/ added.

But there are still oddities, like some window remaining black for like 2~3
seconds after re-mapping.

Closing the skypeforlinux toplevel and restoring it by running it again
triggers the black window for a few second issue (skype doesn't really
quit, it remains running, until it's recalled again, so this is the same
X11 client)

Cheers,
Olivier
