Bug Description

Compositor report inconsistently reports frame time during bypass, and render time otherwise. As of Mir 0.10.0 on mesa it should be reporting render time exclusively (i.e. zero for bypass). Not the frame time.

---------------
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...
