This bug was fixed in the package mir - 0.8.0+14.10.20141005-0ubuntu1 --------------- mir (0.8.0+14.10.20141005-0ubuntu1) 14.09; urgency=medium
[ Daniel van Vugt ] * New upstream release 0.8.0 (https://launchpad.net/mir/+milestone/0.8.0) - Enhancements: . Less sensitivity to ABI breaks - many headers unused by external projects are now hidden and not installed by -dev packaes. If you require any headers that are missing, just ask. . Touchspots: --enable-touchspots to servers; visually shows touch locations (warning: This affects performance LP: #1373692). . Client performance reporting: Any Mir client can now get accurate performance information (frame rate, render time, buffer lag etc) logged to stdout. Just set env MIR_CLIENT_PERF_REPORT=log . Further improved touch responsiveness, with less lag and smoother scrolling (so long as you don't enable touchspots). . Slightly faster builds using precompiled headers. . Turn hardware overlays on by default. When in use, this halves the CPU usage of a Mir server. Already enabled in unity-system-compositor. . More scripting to detect ABI breaks. . Improved src/ tree consistency (renamed "src/shared" to "src/common"). . Improved fatal signal design: Changed from SIGTERM to SIGHUP delivered to clients on unexpected server disconnection. . Improved library/package design to allow concurrent installations of different Mir versions without conflicts. . Fd reception code is now common to client and server. - ABI summary: Servers need rebuilding, but clients do not; . Mirclient ABI unchanged at 8 . Mircommon ABI bumped to 2 . Mirplatform ABI bumped to 3 . Mirserver ABI bumped to 26 - API changes between Mir 0.7 and 0.8: . Lots of headers removed from the public SDK! We have only hidden headers not known to be used by any known projects. Please let us know if anything is missing - https://bugs.launchpad.net/mir/+filebug . graphics::Platform - interface changed significantly. . Lots of server API changes to support touchspots. . File descriptors now passed as type Fd instead of int32_t. - Bug fixes: . [regression] Mir deb packages with versioned names cannot be installed simultaneously any more (LP: #1293944) . A frozen client can hang the whole server (LP: #1350207) . QtMir FTBFS: fatal error: mir/input/input_channel.h: No such file or directory (LP: #1365934) . [regression] platform-api fails to build against Mir 0.8 (LP: #1368354) .

[regression] Compositing is jerky and stutters during touch events (LP: #1372850) . unit test fails: AndroidInputReceiverSetup.slow_raw_input_doesnt_cause_ frameskipping (LP: #1373826) . intermittent hang in TestClientInput (LP: #1338612) . TestClientInput.scene_obscure_motion_events_by_stacking fails intermittently (LP: #1361757) . [regression] First frame is composited as black (even though the client has provided a non-black frame) (LP: #1362444) . Some mali drivers crash after repeatedly creating/destroying the mir compositor threads (LP: #1362841) . [android] SIGTERM to server with connected client causes crash (LP: #1364637) . [regression] acceptance tests fails in ServerDisconnect.causes_client_to_terminate_by_default (LP: #1364772) . [regression] symbol lookup error: /usr/lib/arm-linux-gnueabihf/libmirserver.so.24: undefined symbol: _ZTIN7android7RefBaseE (libmirserver 0.6.1 doesn't work with libmircommon 0.7.0) (LP: #1364890) . [regression] Mir FTBFS with g++-4.8 [error: ISO C++ forbids casting between pointer-to-function and pointer-to-object] (LP: #1366134) . Intermittent CI failure in DemoPrivateProtobuf.client_calls_server (LP: #1367353) . Overly strict libmirplatform* dependencies are blocking CI (LP: #1370866) . [regression] mir demo servers segfault on shutdown (LP: #1371619) . Nested server crashes with SIGSEGV on shutdown in eglDestroyContext() (LP: #1372276) . [regression] Moving/resizing clients in a nested server is very jerky/stuttery (LP: #1372300) . [regression] Bypass/overlays are toggling constantly (LP: #1373689) . [regression] Mir server uses too much CPU during touch scrolling (LP: #1373809) .
