Bug #1497085 “Unity8 crashes when Xmir -rootless opens a second ...” : Bugs : unity8 package : Ubuntu

Unity8 crashes when Xmir -rootless opens a second window (like a menu). I've put some effort into fixing up Xmir's -rootless mode this past week and it works pretty well in Mir's demo servers. However it's held back by Unity8 (mobile and desktop modes). Unity8 just crashes the moment Xmir opens a second window (like a menu even). I understand this arguably not being a supported feature on mobile but on desktop it's pretty important.
