--- Comment #13 from Thomas Lübking <thomas.luebk...@gmail.com> --- It's not exactly your fault either. a) Does that "Football Manager 2016" client never sport (pun intended) a WM_CLASS hint, or did you set it empty manually (because it also adds WM_CLASS late)? b) The pretty much means CEF is setting WM_CLASS after the map request, what's rather an icccm violation Strictly spoken though, it must be set as long as the window is withdrawn, maybe they keep it that state until it gets actually mapped (while that's not helpful ;-) => We might have to sync after mapping the window and before applying the rules? Can you try a patch (for kwin) - doesn't make sense to relax things here if the client sets WM_CLASS some seconds later. -- You are receiving this mail because: You are watching all bug changes.
