[Launchpad Bug Tracker <1312107@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package unity - 7.2.3+14.04.20140826-0ubuntu1

---------------
unity (7.2.3+14.04.20140826-0ubuntu1) trusty; urgency=medium

  [ Andrea Azzarone ]
  * Remove cross fade effect during lock/unlocking. A simple fading
    works just fine. (LP: #1312107)
  * Manually emit nux::Area::geometry_changed beucase nux can fail to
    emit it. (LP: #1292391)

  [ Pawel Szubert ]
  * Reduce the scope of the kill command when restarting Compiz.
    (LP: #1324114)

  [ Marco Trevisan (Treviño) ]
  * LockScreenAcceleratorController: do ther configured action on power
    special keys press. We finally can suspend, shutdown, hibernate or
    start the screensaver when the screen is locked, using the Suspend,
    Sleep, Hibernate and PowerOff hardware keys. Also the Shutdown
    dialog doesn't allow now to lock the session if it is not allowed by
    settings. (LP: #1306211) (LP: #1320051) (LP: #1320071)
  * Previews: scale the dash preview contents to match current monitor
    scaling. Improved also the scaling of search-bar, spinner, categories
    and many other components. (LP: #1339629)
  * FilterWidgets: add support for scaling (LP: #1340171)
  * OverlayRendering: correctly scale the overlays borders and edges to
    match settings. DashStyle has been modified to return smart pointers
    of textures that are loaded depending on the scale level. The cache
    will make sure that we don't duplicate the textures and that they
    get removed when not needed anymore. Also thanks to this the
    SearchBarSpinner textures (and the other spinners as well) uses the
    SVGs scaled at the proper size (I desgined a new SVG for the
    magnifier, as we only had a PNG). (LP: #1283415) (LP: #1340394)
  * Hud: scale to match current DPI settings for monitor. (LP: #1340477)

  [ Eleni Maria Stea ]
  * Previews: scale the dash preview contents to match current monitor
    scaling. Improved also the scaling of search-bar, spinner, categories
    and many other components. (LP: #1339629)

  [ Stephen M. Webb ]
  * Reduce the scope of the kill command when restarting Compiz.
    (LP: #1324114)

  [ Chris Townsend ]
  * Bump version to 7.2.3.

  * Hud: scale to match current DPI settings for monitor. (LP: #1340477)
  * PlacesOverlayVScrollBar and VScrollBarOverlayWindow: add support for
    scaling. Add a new ScrollView class to create ScrollViews with an
    OverlayScrollbar and with scaling support. Using them in dash Scopes and
    Previews. (LP: #1340996)
  * LockScreenShield: Add GrabScreen function and retry to make sure we really
    get the grab. It might happen that the grab is not possible because the
    PluginAdapter::IsScreenGrabbed request has still not being fully processed,
    and thus nux is not able to grab the pointer/keyboard. By doing this we
    instead try to grab the screen, and if this is not happening, we wait a
    little until we don't get the ungrab event. In this way, if we eventually
    get the grab, all will work as expected. Otherwise, we cancel the lock
    request (very unlikely to happen). (LP: #1349128)
  * PlacesOverlayVScrollBar: redirect the mouse wheel scroll events coming from
    the thumb to the scrollview. This will make the scrollview to handle then and
    perform the same scrolling action it would do otherwise. (LP: #1340992)
  * SwitcherView, PanelService: correctly handle horizontal and vertical scroll
    events (LP: #1342208) (LP: #1342731)

Title:
  Minimised applications show briefly before lock and after unlock
  (again)

Status in Unity:
  Fix Committed
Status in Unity 7.2 series:
  In Progress
Status in “unity” package in Ubuntu:
  Fix Released
Status in “unity” source package in Trusty:
  Fix Released

Bug description:
  [Impact]
  With the new locking scheme in unity7, minimized applications appear briefly after unlocking
  Here is a video showing the problem: https://www.dropbox.com/s/ai5r2krtgbo93im/2014-04-24%2009.51.52.mp4

  [Test case]
  1. Open some applications (in my case psensor and steam)
  2. Minimize them
  3. Press CTRL+ALT+L or Super+L to lock the screen
  The minimized windows should never briefly popup before the screen locks.

  4. Unlock screen
  The minimized windows should never re-appear and then re-minimize.

  The minimized applications must stay minimised through the lock/unlock
  process.

  [Regression Potential]
  Nothing known


  There is another bug about this but it is marked as fixed.. so I guess
  the problem wasn't fixed after all? #1291402
