The issue appears to stem from the Main.layoutManager.hotCorners[] array being empty when hot corners are disabled: https://git.gnome.org/browse/gnome-shell-extensions/tree/extensions/apps-menu/extension.js?id=01893ca0485806f181d0401b7a6347a4adaa71de#n483
Would it be possible to leave the Main.layoutManager.hotCorners[] array defined and disable the activity overview by substituting no-op functions for actions? This is how the "No Topleft Hot Corner" extension works: https://github.com/HROMANO/nohotcorner/blob/f02c0398fe59202ba01b35ae04f8fe1fb46008e1/extension.js#L7 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1725941 Title: hotCorner modification breaks official apps-menu extension To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1725941/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
