Ok, I've traced this down to bug #1675448 being the root of the issue.
Xmir is started no matter what and if an application natively supports
Mir such as a Gtk or Qt app, then there are multiple connections to Mir,
which is what the aforementioned bug is about.
So a decision needs to be made.

started (without Xmir) and worked great. but then i closed the app and
the second time it tried to launch with Xmir but failed to load. (not
sure why it tried
@dinamic I think you're seeing a different problem with similar
symptoms, probably related to libSDL2 probing order.
