Title:
  Using Show Desktop (Ctrl+Super+D) twice irreversibly makes Launcher
  and window switcher (Alt+Tab) completely unusable if one window is
  maximized

Status in Unity:
  Expired
Status in unity package in Ubuntu:
  Expired

Bug description:
  Steps to reproduce (don't know if will 100% systematically reproduce or not):
  - show desktop with Ctrl+Super+D
  - go back to normal with Ctrl+Super+D again
  - Maximize a window
  - Move the cursor to the left of the screen

  => 1st glitch: launcher should show up. It doesn't. Hence launcher is
  unusable as long as you have a maximize window now.

  - Now unmaximize the maximized window(s), so you don't have any.
  - try Alt+Tab

  => 2nd glictch: the application switcher (the horizontal bar in the
  center of the screen with a square for every open application) is
  BEHIND ALL WINDOWS!!! Oh my god! Unusable too (whether or not you have
  maximized windows

  - Now hit Ctrl+Super+D again. So now the system is in the "show desktop" kind of state (this two-state thing is a nonsense design in the very first place btw,  but that's another bug)
  - Restore some of the minimized windows, or even all of them, so you still are in the nonsense "show desktop" state but you have a few windows open.
  - Make sure none is maximized
  - Try Alt+Tab, try the Launcher

  => Both work, so this is the only workaround to both glitches: you have to always make sure the total number of times you have hit Ctrl+Super+D is odd, and then unminimize all the windows you need always manually.
  But this will still not solve a third glitch:

  - now maximize a window
  - try the Launcher (i.e. move the mouse all the way to the left)

  => 3rd glitch: the launcher shows up, but it is broken: as soon as you
  move the mouse cursor one pixel to the right it will hide again, so
  you'll never be able to click on any of its icons.

  
  The show-desktop think is completely screwed up and if you use it, the whole desktop becomes an unusable mess where most basic functionality (window switching and the launcher) become inaccessible (until you figure out the intricated way to access them when you discover exactly the pattern of behavior of this bug).
