We now have a /future/ fix landed. But that only works for the cases where the older Mir version is 0.19 and you have something newer than that installed on top of it. Still lacking a retrospective fix, which may just need to be a script or deb rules to force out the old broken packages like: sudo apt-get remove mir-client-platform-mesa2 mir-client-platform-mesa1
