I am not able to reproduce
As of git commit 34027455aaa2ee738c45987ca2d8cb7d65491bf0 window tiling support has been removed from KWin. This change will go into version 4.10, the upcoming release 4.9 still provides window tiling support. The discussion has been taken on the developer mailing list [1]. A short summary of the reasons here: * it is unmaintained * it is a mode not used by any of the core KWin team * original developer said at Akademy 2012 that he is not interested in picking up the work again * tiling has quite some bugs, e.g. multi screen not supported * is conflicting with other concepts in KWin, e.g. activities A result of this change is that we will not implement any new features or fix bugs related to window tiling. There is ongoing work to provide window tiling as an external KWin script. We encourage everyone to participate in this effort and to make it really rock and have it available once 4.10 is going to be released. The current state can be found in the git repository [2] in the directory kwin/scripts/tiling. [1] http://lists.kde.org/?l=kwin&m=133149673110558&w=2 [2] https://github.com/mgottschlag/kwin-tiling/
