Title: Nesting Mir servers with assorted display configs causes lockup Status in Mir: Fix Committed Status in mir package in Ubuntu: New Bug description: Using a mako, with external display attached, flashed with ubuntu-pd and Mir trunk + a few branches: lp:~alan-griffiths/mir/fix-1463873 lp:~alan-griffiths/mir/fullscreen-sticks lp:~alan-griffiths/mir/name-nested-display-for-output lp:~alan-griffiths/mir/more-detailed-log-from-shell-report (The latter three are probably irrelevant, the first one is needed for the scenario to work well enough to see this error.) $ sudo stop lightdm $ cd mir/build $ bin/mir_demo_server --window-manager system-compositor --display-config sidebyside --file /tmp/mir_socket (in a new ssh session) $ cd mir/build $ bin/mir_demo_server --host /tmp/mir_socket --display-config clone (in a new ssh session) $ cd mir/build $ bin/mir_demo_standalone_render_surfaces --no-file --display-config single --host /run/user/32011/mir_socket ^C (This last command can be repeated numerous times without problems manifesting) $ bin/mir_demo_client_egltriangle The triangle is displayed, but doesn't rotate. In the second (nested) session there's an error: [1447687623.835199] <ERROR> MirBufferStream: Error processing incoming buffer error registering graphics buffer for client use Neither the client, not nested server respond to ^C until the host server is stopped with ^C.
