After the recent update to Ubuntu 17.10 and the switch to Gnome, Tint2 still runs but does not show all windows. Specifically, terminal windows do not appear (bot not limited to terminal).
Here is a screenshot, where my current Firefox window is visible but not my terminal.
I've been through all settings of Tint2 without finding any suitable change. The same behavior happens on another computer. If I run a session with Unity instead of Gnome, tint2 works as expected (all windows appear).
Is this a standard behavior ? Is there any known fix ?
