If there were any "crashes" then indeed using a Xorg session you would
not notice them, because gnome-shell on Xorg can restart seamlessly and
your apps are unaffected. That doesn't mean Wayland is crashing more
often than Xorg, only that a Xorg session recovers better from gnome-
shell crashes.

But this bug is not about crashes. It's about app windows not responding
to clicks while the shell does. So if you do experience that problem
then we would like to know how to reproduce it.

We probably don't want any discussions of crashes here because I don't
think they will be relevant. They should get their own separate bug
reports.

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

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
