It's not a duplicate - the approach to fix the other bug caused this one.
Git commit 6a276260906353ebeedcd07abd081c28e67a8163 by Thomas Lübking. Committed on 03/06/2015 at 19:22. Pushed by luebking into branch 'Plasma/5.3'. set still required xcb properties in findRule which is invoked "in place" of the detect button when calling the kcm as special window/application setting from the Alt+F3 menu REVIEW: 123953 M +6 -0 kcmkwin/kwinrules/main.cpp http://commits.kde.org/kwin/6a276260906353ebeedcd07abd081c28e67a8163
