As far as I can tell "-rootless" mode actually is not implemented yet. I can't make it crash but I can see that it mistakenly maps each X Window (some of which could be menus or even individual widgets like in xedit) to separate Mir surfaces. If we're going to continue on this path then Mir needs full sub-surface (child/embedded surfaces) placement support.
