Bug Description

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.

Workaround added to Xmir (it was always going to be needed for phones/tiling shells anyway):

@daniel so is the workaround what we should just rely on here ? considering your "always going to be needed"

Unity8 really needs this fixed soon for desktop mode. Not being able to open menus or dialogs is a big deal.

For the phone shell, it would be nice if Unity8 could handle multiple surfaces there, but understandable if it doesn't (so the flatten option/workaround may always be needed).
