This bug was fixed in the package mir - 0.26.0+17.04.20170126.3-0ubuntu1 --------------- mir (0.26.0+17.04.20170126.3-0ubuntu1) zesty; urgency=medium [ Daniel van Vugt ] * New upstream release 0.26.0 (https://launchpad.net/mir/+milestone/0.26.0) - ABI summary: . mirclient ABI unchanged at 9 . mirserver ABI bumped to 43 . mircommon ABI unchanged at 7 . mirplatform ABI unchanged at 14 . mirprotobuf ABI unchanged at 3 . mirplatformgraphics ABI unchanged at 11 . mirclientplatform ABI unchanged at 5 . mirinputplatform ABI unchanged at 6 . mircore ABI unchanged at 1 - Enhancements: . New/improved toolkit APIs: MirInputConfig and related functions, MirWindow and related functions, DisplayConfig and related functions, MirScreencastSpec and related functions, . Support for configuring input configuration . Introduce toolkit extension mechanism for platform specific APIs. . Toolkit extensions for: mesa_drm_auth, set_gbm_device and window_coordinate_translation . Screencasting to a specific MirBuffer. . Add DisplayConfigurationController::base_configuration() so downstreams can get the base configuration. (Weirdly they can already set it.). . x11 platform: allow adjustable scale parameter. . Added EDID support: client API, server logging and in mirout. . mirout: Add newer attributes only available in the new display config API: scaling factor, subpixel arrangement and form factor. . mirout: Log the orientation and logical size of each output too. . Replace the mir::Server-overridable Reports with Observers. . Add xkbcommon to mirclient.pc Requires.private. . Deprecate legacy toolkit APIs that will be removed in Mir 1.0 . Introduced 'client-side vsync', which dramatically reduces latency from the client to the screen (particularly for nested servers like Unity8). - Bugs fixed: . [performance] Restore support for better-than-triple buffering by default. (LP: #1240909) .

Shell doesn't know when base display config has changed (LP: #1644189) . miral::ActiveOutputsMonitor (and therefore miral-shell --window-manager tiling) are broken by lp:mir (LP: #1645284) . mir_proving_server's four finger swipe to switch apps leaks touch events to the clients (LP: #1646700) .
