This bug was fixed in the package mir - 0.3.0+14.10.20140618.1-0ubuntu1

---------------
mir (0.3.0+14.10.20140618.1-0ubuntu1) utopic; urgency=medium

  [ Cemil Azizoglu ]
  * New upstream release 0.3.0 (https://launchpad.net/mir/+milestone/0.3.0)
    - mirclient ABI unchanged, still at 7. Clients do not need rebuilding.
    - mirserver ABI bumped to 21. Shells need rebuilding.
      . Divide swap_client_buffers into separate functions.
      . Allow buffer swapping even when compositor is turned off or blocked.
        (LP: #1308843, 1308844)
      . Wire the cursor client API through the session mediator to the surface
        observer.
      . Generate destination alpha for alpha enabled display buffers.
      . Named threads.
      . Support for prompt sessions :
        https://wiki.ubuntu.com/Security/TrustStoreAndSessions.

    - mirscreencast screenshots now produce images with correct color instead
      of transparency.
    - Rename bind_to_texture->gl_bind_to_texture.
    - Refinements in test infrastructure.
    - Phablet: allow disabling the overlays via a command line switch.
    - Unify the DisplayBuffer interface's optimization functions
      behind post_renderables_if_optimizable.
    - Clean up the DisplayDevice interface so that it doesn't require the
      functions are called in any particular order.
    - Phablet: graphics: android: preserve buffer ownership for onscreen
      overlay layers until the subsequent display posting.
    - Allow the platform to register emergency cleanup handlers in order to
      restore the graphics system to a sane state when the server fails
      abruptly.

    - Bugs fixed:
       . Mirscreencast outputs translucency instead of shadows, producing
         incorrect images. (LP: #1301210)
       . JSON formatting. (LP: #1324902)
       . Fix input_area_contains to work properly in global coordinates even
         when input_rectangles is updated. (LP: #1261647)
       . Allow a moment for clients to acquire a buffer. (LP: #1317370)
       . Generate correct alpha by changing blending equation to assume
         pre-multiplied alpha sources. (LP: #1318852)
       . Rework the recomposition messaging so that the DisplayBufferCompositor
         is no longer involved. (LP: #1319907)
