cannot launch application from activities overview

[Ilario Sanseverino]

After upgrading Ubuntu from 19.10 to 20.04 I'm not able to launch applications from the overview window. If I right-click on the app, add to favourites and then launch it from the dash it works, but if I just left-click on the app icon nothing happens.

When launch fails in `journalctl /usr/bin/gnome-shell` I get this entry: `clutter_input_device_ungrab: assertion 'CLUTTER_IS_INPUT_DEVICE (device)' failed`

The problem occurs with both X11 and Wayland sessions (although I only checked the journalctl on X11)

Thank you for your bug report, the journal log has several error from HideOverviewWhenClickOverview, could you try if disabling that extension resolves the issue?

[Ilario Sanseverino (ippattume)]

Yes, you are right, that one was the culprit. I didn't even remember to have that extension installed.

thank you, you can close the issue. Sorry for the time you wasted...
