Just wondering if anyone else has experienced in F18 (GNOME3.6) a weird bug where the alt+tab switcher does not disappear?
When it happens, i can press press alt+tab again and other switcher is displayed under (z-index wise) the one already on the screen. If i keep pressing alt+tab, these layer up also.
The annoying part is that when you go to restart the shell, (with alt+f2), that overlay does not get keyboard focus, so you can't restart it from there. The only way to restart the shell is to switch to another tty, and kill the gnome-shell process with kill -9
anyone else experiencing this issue?
cheers, ryanlerch

I had this happen a few weeks back but wrote it off as a heisenbug because for instance, I had numerous updates applied without restarting my session. I haven't seen it since, but it was precisely the symptoms you just identified.

Yep. But as Michael said, I can't reproduce it on demand. It randomly happens. Any logs I could look into the next time it happens?

This just happened to me again.
Here is the tailend of the ~/.cache/gdm/session.log

Does anyone know of a bug that is tracking this on GNOME BZ? If not, i will file a new one.

I do not recall a bug for the alt-tab issue, but the disappearing notification area[1] was fixed with the Gnome Shell 3.6.3 package that was pushed a few days ago. I haven't seen any issues since then.

I just had it happen to me for the first time in weeks, but I cannot seem to find a way to reproduce it.
Have you created the bug?
I have not created another bug, but i think there are a few in the GNOME bugzilla that cover similar issues.
When my last occurrence happened, a notification was displaying at the same time. But i could not reproduce it afterwards either.

OK, I've had it happen to me twice (after not happening for since the last email) this week.
It seems to happen when I change windows using the mouse (clicking on window to gain focus). Both times I was changing from a Pidgin conversation to a Firefox window but I cannot easily reproduce it.
When I clicked on Firefox, my mouse was no longer passing clicks to other windows (including Firefox). My keyboard still functioned, however, ALT+TAB did not function correctly. When I pressed ALT+TAB it did not allow me to switch windows, but instead kept adding a new ALT+TAB window over the previous one each time I pressed the keys.
I could use the mouse on the ALT+TAB window, and reduce the ALT+TAB windows by clicking on an item. After killing gnome-shell and restarting it my mouse/keyboard returned to normal.
From this account, I feel there is a race condition somewhere involving
mouse focus/control in gnome-shell or it may be a GTK3 bug.
I'm uncertain opening a bug would be fruitful as Red Hat maintainers ignore Gnome bugs for non-rawhide versions and I cannot run rawhide on this system.

We have quite a variety of bugs of this form around focus handling. It's a tricky problem domain, and hard to test. If you can figure out how to reproduce the problems, that helps a lot.
If it feels like it happens "randomly", most likely it's triggered by a concurrent event (for example, a message tray notification appears while you have alt-tab up).
