Bug Description

After the most recent Lunar updates (i.e., with the newest GNOME) my gnome-shell got into a state where clicking on the title bar of a window wouldn't raise the window (or do anything else), while clicking inside the window raised it as expected. The problem went away after I rebooted. I think this may have occurred after some other aberrant behavior, specifically the shell hanging for about 30 seconds (I will file a separate bug about that), so it's possible that things were in some sort of broken state because of that and this bug isn't actually specifically about the title bar, but I thought I should file a bug report about it just in case it's something other people start seeing so we can see how frequently it's happening.

This issue is NOT fixed in 44.1-1ubuntu1. I don't know whether that's because the fix from upstream didn't get included in that package somehow, or whether the upstream bug is not actually the root cause of the issue reported here. If I launch an emacs window with the new version of mutter in mantic, clicking on the title bar still doesn't raise the window, whereas clicking on the title bar of a terminal window DOES raise it. I.e., the problem I initially reported above still exists.

While this was the first bug logged, we failed to notice when duplicate bug 2013216 was reported and most of the discussion has now occurred there. So we should use bug 2013216 as the primary bug. Feel free to reopen that too if you're confident that it's not fixed in Ubuntu 23.10.

It looks like this bug is specific to the setting you have:

  gsettings set org.gnome.desktop.wm.preferences focus-mode 'mouse'

So please try the default instead:

  gsettings set org.gnome.desktop.wm.preferences focus-mode 'click'

summary: - gnome-shell gets into state where clicking on window title bars doesn't
- raise them
+ When focus-mode=mouse is set, gnome-shell gets into state where clicking

https://gitlab.gnome.org/GNOME/mutter/-/issues/2817 is kind of similar but is about:

  gsettings set org.gnome.desktop.wm.preferences focus-mode 'sloppy'

So basically it looks like the fix in 44.1 only works for the default:

  gsettings set org.gnome.desktop.wm.preferences focus-mode 'click'

OK, yes, it turns out that mouse focus vs. click focus is indeed the differentiator for me, but it's a bit more complicated than that. If I have focus set to mouse when I log in, then this bug manifests even if I change focus to click. If I have focus set to click when I log in, then this bug does not occur even if I change focus to mouse. So the deciding factor seems to be the focus setting that's active at the time the user logs in.

It looks like the gnome bug does acknowledge it only works for 'click' mode (I use sloppy) so presumably when that gets fixed (and it looks like they're still thinking about it!) and released then both mine and yours will too.
