[Bug 969039] Re: HUD appears when tapping Alt+Left very quickly

 

This bug was fixed in the package unity - 7.1.1+13.10.20131004-0ubuntu1

---------------
unity (7.1.1+13.10.20131004-0ubuntu1) saucy; urgency=low

  [ Brandon Schaefer ]
  * Break the bump detection by moving to the first icon, then down 5
    pixels. Since bump detection needs to move in 3 different
    directions.
  * Move the switcher Alt+<ArrowKey> shortcut handling into nux, from
    compiz. Now nux handles these events instead of compiz. This way its
    makes much more sense code wise and we no longer ungrab the arrow
    gets from X... so Alt+LeftArrow will no longer open the hud. (LP:
    #969039)

  [ Andrea Azzarone ]
  * Fix bad redrawing of dash overlay scrollbar connector. (LP:
    #1233195)
  * Update icon_under_mouse before process mouse movemnt in the tooltip
    manager. (LP: #1172769, #1233666)
  * Hide the tooltip when an app is closed. (LP: #1172769)

  [ Marco Trevisan (Treviño) ]
  * TestIMTextEntry: fix failing tests with IBus, use TEST_F and TEST_P.
  * CairoBaseWindow: only regenerate blur texture when visible and
    damaged. (LP: #1233109)
  * CairoBaseWindow: add fade animator to control both QL and Tooltip
    Removing the animator from LauncherIcon, and handling the tooltip
    animation inside the QL and Tooltip base class.
  * PanelService: close a menu and re-send the keyevent when handling a
    combination Or when we try to open HUD/Dash. Also, close the active
    menu if a new application is opened and focused. (LP: #10905,
    #1234457, #1197071)
  * SimpleLauncherIcon: we need to restore the focus when closing the
    Overlay for activation. (LP: #909870)
  * LauncherIcon: don't try to show again quicklists or tooltip if
    center changed, just move them. (LP: #1234778)
  * AbstractLauncherIcon: add static icon_size property. (LP: #1073103)

  [ Christopher Lee ]
  * Preparing autopilot tests for an upcoming update in autopilot 1.3.

  [ Ubuntu daily release ]
  * Automatic snapshot from revision 3554

Bug description:
  When I press Alt plus any cursor key in quick succession, the HUD
  erroneously appears. This steals focus and disrupts the workflow quite
  severely. This was much worse in earlier Unity versions, 5.8 already
  made this a lot better. But this case still remains for me.

  When I leave some time (0.5 s or so) between pressing Alt and the
  cursor key, this does not happen. But when pressing them almost at the
  same time, the bug happens. I can reproduce this 100%, so feel free to
  ask for any additional debugging info.

  The problem is not that I hit the Cursor key before alt. This proves
  it:

  $ xev | grep -A2 ^KeyPress
  KeyPress event, serial 36, synthetic NO, window 0x3800001,
      root 0xbe, subw 0x0, time 17590219, (112,69), root:(113,867),
      state 0x0, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,

      state 0x8, keycode 113 (keysym 0xff51, Left), same_screen YES,

  and I get the HUD.

  It does not matter which application/window is focussed. It happens in
  gnome-terminal, Firefox, or the blank desktop all alike.

  It does not happen with other Alt key combinations, just with the
  cursor keys. I also saw this happen quite a lot with Ctrl+Alt
  (controlling screen grab in KVM) or Ctrl+Alt+Cursor (changing
  workspaces), but I cannot reliably reproduce those.
