Bug#792057: kwin-x11: Moving and resizing windows breaks for all applications when using clusterssh
Package: kwin-x11
Version: 4:5.3.2-1
Severity: important
Dear Maintainer,
kwin_x11 stops handling window move and resize requests for all windows when using clusterssh. This seems to happen when clicking inside the main CSSH control window, but only after clusterssh has opened and placed xterm windows. Before any xterms have been created by clusterssh, it's interface can be used without breaking kwin_x11. Running kwin_x11 --replace fixes the issue, but breaks again once you try to use the main clusterssh window again. The problems are not experience when using the xfwm4 or metacity window managers (via xfwm4 --replace and metacity --replace respectively). I'm not aware of any other applications that use the X11 protocol to control window geometry and placement. If there are others, they may be affected as well.
The following are the message displayed from kwin_x11 just after creating a terminal and clicking in the CSSH control window:

It should be noted that I have been using window rules to force KDE4's kwin to use the application's requested geometry and placement. The windows management breakage happened with an empty set of rules immediately after installing kwin_x11, and after creating windows rules.
Steps reproduce:
1) start clusterssh and add ssh connections with it
2) click in the CSSH windows again, window management is now broken.
Expected outcome:
kwin_x11 should be able to handle X11 geometry and window events generated by clusterssh.
