I can reliably reproduce this issue by clicking either Activities on the
top bar, or by clicking "Show Applications" on the dock.

With the latter, the Applications Search dialogue comes up, but no icons
are shown for recent applications. All applications are shown as
expected.

Once the Search dialogue is displayed, I cannot close it. I can launch a
program from the All page, and the application starts, but I cannot
interact with it. If I switch into a console and kill the application,
the search dialogue is still present.

Like with other users, once the bug is triggered I cannot interact with
anything on the screen except for items on the top bar situated on the
right side of the screen (including the date and time at the center).

To work around I have to switch to a console (Ctrl-Alt-F3), and 'pkill
-9 gnome-shell', followed by 'DISPLAY=":0" gnome-shell'. I can then
switch back to the graphical interface with Ctrl-Alt-F2. This *usually*
works for me, but of course YMMV.

I only noticed this bug when I upgraded my main machine today. I have
another similar system which I updated a few weeks ago. In using that I
experienced none of these issues. That system was updated today and it
now shows the same behaviour, so whatever the bug is, it was introduced
very recently.

Title:
  gnome-shell randomly blocks mouse clicks from working in app windows

Status in GNOME Shell:
  Confirmed

Bug description:
  Under GNOME 3, the use of the mouse-click stops occasionally, though I
  can still move the mouse around and can still click on items in the
  Activities screen and the top-bar.

  I can use alt-tab to cycle windows and can still type into already-
  active textboxes in windows, but I cannot click within the windows,
  and the mouse is not picked up at all by the windows.

  I can open the alt-f2 "run command" dialogue, but cannot type into it.

  The workaround I'm using is to open terminal (ctrl-alt-T) and run
  "gnome-shell -r", and restarting that command every time I have the
  problem again.

  Please ask if there's anything I forgot to mention.

  ADDITIONAL: The error tends to happen randomly, but it seems to happen
  upon opening a new window, changing windows, closing windows, or
  opening the activities pane (whether a change of window is thus
  instigated or not)

  ADDITIONAL 2: (sorry, it's early) The other workaround is to log out
  and to log in again, but that is also less than ideal
