This bug was fixed in the package mir - 0.11.0+15.04.20150209.1-0ubuntu1 --------------- mir (0.11.0+15.04.20150209.1-0ubuntu1) vivid; urgency=medium
[ Daniel van Vugt ] * New upstream release 0.11.0 (https://launchpad.net/mir/+milestone/0.11.0) - Enhancements: . Lots more major plumbing in the Android code, on the path to supporting external displays. . Add support for clang 3.6. . Major redesign of server classes in mir::shell,scene and friends (still in progress). . Added client API for creating dialogs and tooltips. . Added new surface states: mir_surface_state_hidden and mir_surface_state_horizmaximized. . Performance: Use optimally efficient fragment shading when possible. . Performance: (Desktop) Composite using double buffering instead of triple to reduce visible lag. . mir_proving_server: Can now resize windows from any edge or corner using the existing Alt+middlebuttondrag. . mir_proving_server: Added some demo custom shaders (negative and high contrast modes: Super+N/C). . mir_proving_server: Can now close clients politely via Alt+F4. . Added MirPointerInputEvent (part of the new input API, the old MirMotionEvent is still supported also for now). - ABI summary: Servers need rebuilding, but clients do not; . Mirclient ABI unchanged at 8 . Mircommon ABI unchanged at 3 . Mirplatform ABI bumped to 6 . Mirserver ABI bumped to 29 - Bug fixes: . [regression] mir_demo_server exits immediately with boost bad_any_cast exception (LP: #1414630) . need way to position menus and tooltips (relative positioning to parent) (LP: #1324101) . GLibMainLoopTest failure seen in CI (LP: #1413748) . Clang builds fail in CI (LP: #1416317) . segfault in mir::compositor::GLProgramFamily::Shader::init() (LP: #1416482) . GLRenderer: The default fragment shader is sub-optimal for alpha=1.0 (LP: #1350674) . mesa::DisplayBuffer::post_update is triple buffered - more laggy than it needs to be (LP: #1350725) . Cannot connect to nested server when started from a differen vt (LP: #1379266) . [testfail] AsioMainLoopAlarmTest fails in CI (LP: #1392256) . Compositor report inconsistently reports frame time during bypass, and render time otherwise (LP: #1408906) . [regression] mir_demo_client_fingerpaint doesn't paint anything any more (with the mouse) (LP: #1413139) . Hardware cursor is always slightly ahead of the composited image (LP: #1274408) . integration tests are outputting (too many) DisplayServer log messages (LP: #1408231) . [regression] deploy-and-test.sh doesn't work any more (unless you have umockdev installed already) (LP: #1413479) . Color Inverse on display. Toggle Negative Image (LP: #1400580) . mir-ubuntu-vivid-armhf-ci fails consistently (LP: #1407863) . Double-buffered surfaces may lag or freeze if event driven and not constantly redrawing (LP: #1395581) . Pointer motion and crossing events are missing (LP: #1417650) -- Ubuntu daily release <[email protected]> Mon, 09 Feb 2015 21:27:35 +0000 ** Changed in: mir (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1416482 Title: segfault in mir::compositor::GLProgramFamily::Shader::init() Status in Mir: Fix Committed Status in mir package in Ubuntu: Fix Released Bug description: This is intermittent (so I'm not sure if there are other ways to reproduce) but Initial experiments suggest this comes of running mir_demo_server with the option "--display-config sidebyside" (and two monitors).
