The proof the client is really still rendering while the composited image appears frozen is in MIR_CLIENT_PERF_REPORT=log. Using that you can see the client is still rendering at a high rate but it also shows the client has been starved of one of its three buffers during the freeze.
** Summary changed: - Clients using swap interval zero in Unity8 freeze regularly. Need to interact with the shell to unfreeze them. + Apps appear to freeze in Unity8, although they are really still rendering (swap interval zero). Need to interact with the shell to unfreeze it. ** Description changed: - Clients using swap interval zero in Unity8 freeze regularly.

Test case (on a phone): $ mir_demo_client_target -n--desktop_file_hint=unity8 + This freezes very quickly when you move your finger around. ** Tags added: xmir -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1497828 Title: Apps appear to freeze in Unity8, although they are really still rendering (swap interval zero).
