Created attachment 108659 [details] Screenshot of task switcher in action Application specific task switcher, by default bound to Alt+`, does not work for certain applications. In the attachment, I have two Dolphin windows open, I press Alt+`, but the task switcher only register one of the Dolphins. This is not the case with GTK applications. For instance, I can have two instances of Firefox open, and Alt+` works fine. Also, Alt+Tab works without problems no matter which windows are open. It is specifically Alt+` on KDE applications that seems to have a bug. I'm using Arch Linux and this issue emerged after an update at around Oct 11.
