[Bug 892012] Re: Window management - When a semi-maximised a window is maximised and then restored, the window position jumps and window size changes so the the window title bar is sometimes hidden underneath the top bar

 

Reverting bug to triarged as issue is not completly fixed, see note
added to top of description.

** Description changed:

+ Note: reverting bug to triarged because the fix is not complete.  When
+ tested the correct behavour of "the window should return to exactly the
+ same state it had at the beginning of step 1." is not fulfilled.
+ 
+ -----------------------------------
+ 
  Window management - When a  Semi-maximising a window is maximised by
  clicking on the window decorations and then returned to the semi-
  maximised state, the window position jumps so the the window title bar
  is hidden underneath the top bar.
  
  One way reproduce the bug:
  1. Take a restored window
  2. Semi-maximise the window
  3. Press CTRL + SUPER + UP ARROW to maximise the window
  4. Click on the 'restore' window decoration to return the window to the restored state state.
  
  What currently incorrectly happens:
  - After performing step 3, the window returns to a weird state where it is restored, but in the size and shape of a semi-maximised window, and the position is also offset from what would be expected from a semi-maximised window.  This is especially problematic because in some cases the window is positioned so that all of the window title bar is underneath the top bar, making it impossible for a user to move the window without knowing a keyboard shortcut.
  
  See the attached screencast "window_positioning_issue.ogv" to see the
  bug in action.  (In the screencast this bug is reproduced using the
  window decorations instead of the Alt+F10 shortcut, which won't be
  possible after bug https://bugs.launchpad.net/ayatana-design/+bug/796594
  is fixed)
  
  Desired behavour:
  - On pressing the 'restore' window decoration in step 4 of the bug reproduction instructions, the window should return to exactly the same state it had at the beginning of step 1.
  - When fixing this bug, also review and look at fixing bug https://bugs.launchpad.net/ayatana-design/+bug/796594 as these issues are related
  
  -------------------------------------------
  
  Another way to reproduce the bug:
  1. Semi-maximise the Thunderbird main window
  2. Press the 'restore' window decoration (button on the far right of the 3 button cluster)
  
  What currently incorrectly happens:
  - The window jumps up so that the window title bar in underneath the top bar
  
  What should happen
  - The window should return to it's previous 'restored' state.
