If Task Manager settings are set to group windows, but "Only when the task manager is full", then some instances of a program window do not get grouped with the other instances. This is confusing, as you now have two places to look for a given window. For example, when I want to switch to one of your browser windows I always have to look at both the lone instance of it and the group to find the one I want, which is worse than having them all grouped together or all separate. Reproducible: Always Steps to Reproduce: I have a panel going across a display 1920 pixels wide, set to group windows only when full (sorted alphabetically, if that matters). I have the following windows which are restored when the session starts: 5 x Firefox 1 x konsole 1 x konversation N x gvim 1 x okular 1 x dolphin Actual Results: When the session starts I get all gvim windows grouped together, but four Firefox windows grouped together and one Firefox window is on its own. It's not even the first Firefox window, it seems to be a random one each time, so I don't even get any consistency between session restarts. Expected Results: All Firefox windows should be grouped together.
Is one of the Firefox windows in notification state? They are automatically ungrouped. If not, please provide xprop and xwininfo output for both one of the grouped windows and the ungrouped window.
