I can't seem to reproduce any such issue with Mir demo servers or Xmir. Old clients including Xmir work just fine when run against Mir 0.23 and lp:mir for me.
Admittedly I haven't tested the critical combination of Mir 0.23 + Unity8. I expect you have too many variables though. When you upgraded to Mir 0.23.0 you probably also upgraded Unity8, QtMir etc. There's no telling which project contains the bug... -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1584784 Title: 0.23 xapps need interaction to start in pocket-desktop To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1584784/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
