Clicking twice on app list messes up overview (race condition)

Created attachment 294512 [details] overview messed up See the attachment, this is what I'm able to reliably recreate. And this is how to do it: 1. open some window, e.g. nautilus 2. restart gnome-shell with alt+f2 -> r. The bug only occurs the first time app icons are displayed (a race condition while loading the icons). Maybe it's a general issue, but I'm not fast enough once the icons are loaded. 3. open the overview 4. click on the app list icon (9 dot icon in dash) twice very fast. You can see you were successful if you see app list, but there are no "frequent" and "all" buttons at the bottom 5. close the overview 6. open the overview. voila, you screen is messed up, both views in overview are blended together. both are actionable. 7. get rid of the problem by showing the app list and closing it once again gnome-shell-3.14.3-1.fc21.x86_64

This might be possible to trigger only in a VM, when effects are disabled. I have not succeeded in reproducing this on bare metal, where there is that flying icons animation.
(In reply to comment #2) > This might be possible to trigger only in a VM, when effects are disabled. You can manually disable animations on bare metal as well, by running Gtk.Settings.get_default().gtk_enable_animations = false in looking glass (alt-f2 lg). However I haven't been successful in reproducing the race so far ...
I tried disabling animations and I can't reproduce it on bare metal either. Maybe my PC is too fast. But in VM I can reproduce every time. And I don't even need to be particularly fast, I can afford a 0.5 - 1 sec delay between the clicks, and I still trigger it. Don't forget to restart gnome-shell every time you try it, it happens only on the first attempt after restart.

This is something I reported in Fedora but I'm gonna talk about it here anyway: I noticed that when fedora (25 and earlier versions) boots for the first time using a live image without being installed, the activities overview overlay the applications overview. At first I thought the issue was with the ESC key but then I realized that the issue is not with the ESC key but the "show applications" button, this can be reproduced only when fedora boots for the first time from a live image, I'm not sure if it's possible to reproduce after a fresh system installation, this is how I found the bug: 1. Press windows key or click on Activities at the left top corner. 2. Press once "show applications" button, you'll see all the applications pre-installed in the live image. 3. Press "show applications" button once again, you'll notice that the applications icons won't go away. 4. Without leaving there, open any of the apps on the dock, for example, open files. 5. Once files is open, go back to activities overview using windows key or click on "Activities" at the left top corner. 6. You'll see now the activities overview overlay the applications overview. 7. To fix the issue, you need to click on "show applications" button again to display what's behind (applications overview), after that everything should work as it should, but I'm not sure if this happens again in other sessions.

I think this is same with https://bugzilla.gnome.org/show_bug.cgi?id=774381
