Marco, I tried the extension level patch at https://github.com/micheleg/dash- to-dock/issues/128#issuecomment-432913072.
Here are my findings... #1 It worked great for preventing two instances of am application from launching when touching an icon on the dock. #2 However, touching the App Grid Icon still does not work. (It seems like the App Grid is unresponsive, but what is really happening is that the applications overview appears briefly and suddenly disappears, as if you had tapped on the App grid Icon twice). Does the fix at https://gitlab.gnome.org/GNOME/gnome- shell/merge_requests/272 resolve item #2 above? System Info... $ lsb_release --all No LSB modules are available.
