Xmir (through no choice of its own) is told to destroy all resources
(destroy xmir_screen) when the last client disconnects. We could make
Xmir leak its resources (including the connection to the Mir server)...
that would also solve some annoying flickering but I'm not sure it's the
right answer.
BTW, I've been hacking Xmir for a week and a half and cannot reproduce
this bug yet. Although I have been using Mir 0.15 (wily) the whole time
too. So Incomplete.

For me I found much improved stability on client disconnection after
this fix:

The trigger is the X server resetting - this occurs when the last X
client disconnects. This causes the root window to be destroyed and re-
created. Thus the Mir surface is destroyed and then (attempted to be)
recreated.
This occurs when running XMir inside a Unity 8 session, other cases that

I wonder if this is another case of Mir choosing the wrong version of
the right driver (bug 1488500). Can you please list all mir debs you
have installed?

Most definitely not the lack of the graphics drivers as I have those
installed on my machine and have a working Unity 8 desktop session.
Another data point is that this doesn't occur when running against
mir_demo_server, but only when running in a Unity 8 desktop session. I
start an Xmir
What version of XMir? I'm not getting any crashing here.

That error looks like one of the cryptic messages you'll get if you

I'm not sure if Xmir crashes. I ran xprop w/ gdb and it just seems Xmir
exits when the client closes the display. I also don't get any crash
file nor any evidence of a core dump.

Ok, it might not be a crash per se, but it's definitely still printing
fatal server error in the logs.
