This bug was fixed in the package mir - 0.15.0+15.10.20150818-0ubuntu1 --------------- mir (0.15.0+15.10.20150818-0ubuntu1) wily; urgency=medium
[ Daniel van Vugt ] * New upstream release 0.15.0 (https://launchpad.net/mir/+milestone/0.15.0) - ABI summary: Only servers and graphics drivers need rebuilding; . Mirclient ABI unchanged at 9 . Mirserver ABI bumped to 33 . Mircommon ABI unchanged at 5 . Mirplatform ABI bumped to 9 - Enhancements: . Add support for Mir-on-X11. . Latency reduction optimizations (around ~15ms reduction in total): Reduced input event resampling latency by 5ms. Reduced output latency (in system compositors) by around 10ms with the introduction of "predictive bypass". And we're not finished; future Mir releases should reduce latency further. . Introduced a python3-based Mir performance framework. . Lots of preparation for an architectural overhaul of buffer swapping, required in the least to support future optimizations like nested bypass. . Added a new cursor: crosshair . Added support for 15/16-bit client pixel formats ("high colour"). . Added a new client function to make picking the right pixel format for a given EGLConfig super simple: mir_connection_get_egl_pixel_format . Added application-not-responding detection . Added client API for specifying input region shape. . Fixed the remaining threading flaws identified by ThreadSanitizer and turned it on permanently for all continuous integration in future. . Added support for relative pointer motion events (e.g. for gaming). - Bug fixes: . Fix focus issues breaking autopilot tests entering text (LP: #1468029) . Fix mir tests failure on armhf with GCC5 (LP: #1478213) . mir_buffer_stream_swap_buffers_sync can hang constraints (LP: #1479899) . Loading libmirclient.so twice leads to a segfault in libmirprotobuf.so (LP: #1391976) . Visible corruption in SDL apps (LP: #1460149) . MultiThreadedCompositor::destroy_compositing_threads hangs/deadlocks on shutdown or display reconfiguration (LP: #1471909) . ctest/"make test" reports 100% tests pass even when some fail. (LP: #1472911) . Mir server crashed - GLib-CRITICAL **: g_source_get_context: assertion 'source->context != NULL || !SOURCE_DESTROYED (source)' failed (LP: #1473869) . USC crash on multimonitor unplug [std::exception::what: error during hwc prepare()] (LP: #1474891) . [regression] Input focus delay after switching app back into focus (LP: #1480654) .

[regression] Demo servers crash on start-up if MIR_ENABLE_TESTS=OFF (LP: #1439078) . [regression] The software cursor has a rectangular shadow around it in mir_proving_server (LP: #1447911) . TestClientCursorAPI.cursor_passed_through_nested_server fails intermittently (LP: #1462088) . [enhancement] Add support for high colour (15/16-bit colour) clients (LP: #1469673) . android-input logs are not flushed as soon as they happen (LP #1470204) . Android: rotated display config not applied when an external monitor is hot-plugged (LP: #1471858) . [regression] Clients are blocked in swap buffers when the screen turns off (LP: #1475120) . [regression] Some Mir EGL demos don't get bypassed any more in fullscreen (LP: #1480755) . [regression] Multi-finger gestures are often not detected as finished (LP: #1481570) . Connection error when no client-platform (drivers) installed is confusing (LP: #1473268) . Compositor report shows overlays ("bypass") is never used by mir_proving_server on Android, even for fullscreen surfaces (LP: #1474231) -- CI Train Bot <ci-train-...@canonical.com> Tue, 18 Aug 2015 21:42:12 +0000 ** Changed in: mir (Ubuntu) Status: Invalid => 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/1475120 Title: [regression] Clients are blocked in swap buffers when the screen turns off Status in Mir: Fix Committed Status in mir package in Ubuntu: Fix Released Bug description: [regression] Clients are blocked in swap buffers when the screen turns off. This came about since dynamic double buffering was introduced in r2763. With triple buffers, the screen turning off just makes clients slow down to 10Hz. However since r2763, well performing clients that are given double buffers will be blocked when the screen turns off. IMHO, the 10Hz behaviour is a mistake for Ubuntu's power management. It's a historical kludge we implemented to support buggy apps, but it's still a supported feature and so should continue to work.
