Pressing the "Show Applications" button from the dock doesn't actually pop up the application launcher. It shows the "swarm" animation, overlaying the current window, and then disappears. If you go into overview mode and then press the button, it behaves as expected. Clicking the button with a mouse also behaves as expected.

This is part of a variety of incompatibilities with touch screen events #128. As stated elsewhere, I can't test thus easily develop any touch related stuff.

As a workaround, I am able to obtain the desired behavior by long-pressing the button.
Tested on Yoga 2 Pro, GNOME 3.18, Arch.

Thanks for the additional information. I might be able to get occasional access to a touchscreen system, so I hope I will be finally able to solve this issue and improve touch interaction.

hmm I had this issue years ago... seems like it also affects "Window list" extension where trying to select a window would not work by touch so I would assume it is the same bug.

Link to extension: https://extensions.gnome.org/extension/602/window-list/

Also, the whole shell with windows become unresponsible for touscreen activity after the gesture to call overview (finger-swipe from left) is used, though it doesn't work when the dock is visible. I think that is a related thing: is also occurs when the dock is visible without overview mode.

As a workaround, I am able to obtain the desired behavior by long-pressing the button.

On my Lenovo X1 Carbon it's actually 1.) long-pressing (to make the applications grid appear) and then 2.) slowly swiping the finger away from the icon-button (so that - seemingly - a release-button event is not triggered).

This behavior is fairly easy and consistent to reproduce, and doesn't seem to be dependent on any specific computer model or brand.

I think this is related as well:

Yes these are related, and basically the same issue, and a proposed fix is at https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/272

It can be fixed also at extension level, following more or less what said here: #128 (comment), however in this case the notify::checked on showAppsButton should be wrapped and everytime we get this signal we should verify the current clutter event that generated it, and in case ignore the change.

This is now fixed for latest gnome-shell and cherry-picked to 3.28 and 3.30.

If there's interest we could fix this at extension level either for older shell versions, it can be done as explained in #196 (comment)

I think we can close the bug here, unless there's interest in workaround the issue at this level.
