[Bug 1536398] Re: Windows disappear without user input and aren't found again on any desks but process still running in background


** Description changed:

  Was working with a LibreOffice document and all of a sudden, window
  looked to be minimizing on it's own. However, it is not located on any
  of the three virtual desks, but is still running as a process. I can
  continue opening and closing new LO windows. Alt+Tab no longer shows the
- now "hidden" LO document.
+ now "hidden" LO document. This has only been intermittently reproducible
+ infrequently with LibreOffice.
- Also, this is not reproducible in gnome-session-flashback (Metacity) so
- this is correlated to using compiz.
+ This also happens on a Toshiba Satellite S55-C5247 with Intel integrated
+ graphics, so not correlated to graphics driver (radeon, fglrx, or i915).
+ In addition, this is not reproducible in gnome-session-flashback
+ (Metacity) so this is correlated to using compiz.
  After restarting the application, it happened again, but this time I could go to another virtual disk and click on it, which would cause it to move to another virtual desk. Secondary clicking the window showed it was both minimized and maximized simultaneously, as it noted:
  WORKAROUND: If I open a blank document and click "Exit LibreOffice" it
  offers to save the hidden document.
