There seems to be an ICCM (Inter-Client Communication Conventions) violation made by LibreOffice on X11. http://tronche.com/gui/x/icccm/sec-4.html The end result of this is the window manager not being able to group the LibreOffice windows correctly. Originally reported to KDE: https://bugs.kde.org/show_bug.cgi?id=335741 See this comment in particular (KWin developer): https://bugs.kde.org/show_bug.cgi?id=335741#c8 Operating System: Linux (Other) Version: 4.2.4.2 release
Lubos: Can you confirm that this is our bug? Thanks!
@Shimi Chen is this still happening with LibO 4.3.5.2 ?
This is no longer happening in 4.3.5.2.
