This bug was fixed in the package mir - 0.26.1+17.04.20170209.1-0ubuntu1 --------------- mir (0.26.1+17.04.20170209.1-0ubuntu1) zesty; urgency=medium
* New upstream release 0.26.1 (https://launchpad.net/mir/+milestone/0.26.1) - ABI summary: . mirclient ABI unchanged at 9 . mirserver ABI unchanged at 43 . mircommon ABI unchanged at 7 . mirplatform ABI bumped to 15 . mirprotobuf ABI unchanged at 3 . mirplatformgraphics ABI bumped to 12 . mirclientplatform ABI unchanged at 5 . mirinputplatform ABI unchanged at 6 . mircore ABI unchanged at 1 - Enhancements: . Support for MirBuffer API that allows for better management of hardware/software buffers. . Support for MirPresentationChain API that allows better control over {de}queueing of individual buffers {from}to the server. . Interim support for MirRenderSurface API that provides a unit of renderable for lower level content such as MirBufferStreams and MirPresentationChains, etc.. MirRenderSurface API is marked deprecated as it (and the relevant entry points) will be renamed to MirSurface before general availability. It will initially be used for revamping support for EGL drivers. . Synchronous version of mir_prompt_session_new_fds_for_prompt_providers() API (mir_prompt_session_new_fds_for_prompt_providers_sync()) added for convenience. . Better name for MirPersistentId-->MirWindowId. MirPersistentId has now been deprecated. - Bugs fixed: . [regression] Unity8 stutters constantly (like half frame rate). (LP: #1661128) . mir 0.26 - spinner loading animation, minimize, maximize too fast. (LP: #1661072) . [regression] Nested server segfaults or rapidly logs exceptions when a fullscreen client starts [in mir_presentation_chain_set_dropping_mode ... std::exception::what: Operation not permitted] (LP: #1661508) . mir_window_request_persistent_id_sync seg faults when called twice. (LP: #1661704) . [regression] Windowed clients of nested servers are all black. (LP: #1661521) . Mir graphics platform ABI broke in series 0.26 but sonames never changed (LP: #1662455) . Fixes for 0.26 changelog. . [regression] mirscreencast hangs during screencast creation. (LP: #1662997) . libmirclient-dev missing build dependency on libmircore-dev. (LP: #1662942) . mir_window_spec_set_cursor_name() doesn't trigger mir::scene::SurfaceObserver::cursor_image_set_to. (LP: #1663197) . [regression] Software clients of nested servers are all black in Mir 0.25.0 and later.
