[Bug 1020141] Re: Restored window showed white after Scale effect

 

** Description changed:

  up-to-date Ubuntu 12.04 64bits, 3.2.0-26-generic, with nvidia
  restrictive drivers (post-release version)
  
  compiz 1:0.9.7.8-0ubuntu1
  compiz-plugins 1:0.9.7.8-0ubuntu1
  compiz-plugins-default 1:0.9.7.8-0ubuntu1
  
  Steps to reproduce
  1) Open any window, a Terminal or nautilus will do
  2) Minimize the window
  3) Activate Scale effect (Super/Win Key + w in Unity)
- 4) Deactivate the effect (Esc o super+w again)
+ 4) Deactivate the effect (Esc or super+w again)
  5) Restore the minimized window (click its icon or alt+tab)
  
  Expected:
  the window shows normally, i.e. with all its contents
  
  What Happened instead:
  The window shows only with its border and titlebar, but a clean white surface. No other content.
  
  I think it is a regression, this has happen before and corrected if I
  remember correctly. Couldn't find other report of this bug.
