It doesn't detect it. Even now when I try to create a new rule for it, I get these lines via the "Detect window properties" button: wmclass= wmclasscomplete=false wmclassmatch=1 > 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 withdrawn, maybe they keep it that state until it gets actually mapped 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. I'm currently running a KWin from an offical Arch Linux package, but I could try applying a patch and compiling kwin, as long as I can apply it on top of the 5.5.4 tag. -- You are receiving this mail because: You are watching all bug changes.
