Interesting, this should never happen. It would be interesting to have a bt of the WebProcess too. So, basically the WebProcess is sending the sync message CreatePluginContainer to the UI process. That happens from NetscapePluginX11::create(), but NetscapePluginX11 is only created by NetscapePluginUnix when the display is X11 one:

#if PLATFORM(X11)
    if (PlatformDisplay::sharedDisplay().type() == PlatformDisplay::Type::X11) {
        m_impl = NetscapePluginX11::create(*this);
        if (!m_impl)
            return false;
    }
#endif

So, this means that for some reason in Wayland we have an X11 sharedDisplay at this point in the Web process. How is that possible? Could it be the fallback X11 display we create when GTK+ doesn't have an open display? See bug #164917. If that was the case, it's impossible that anything could be rendered.
