UI experiences delay when menu / tooltip disappears

[SimonWerner]

Sometimes the system will not respond to mouse clicks or keypresses. This appears to happen when I hold the mouse over an item and a pop-up tooltip appears, or when I click on a menu. I believe it happens when the tooltip/menu is set to disappear.

Steps to reproduce are:
 1) Select a menu item
 2) Click outside the menu
 3) The click won't register for around 7 or 8 seconds. No other keypresses register immediately but will occur around 7 seconds later.

This occurs in GNOME, GNOME applications and also for non-GNOME applications such as Firefox and Chrome.

I raised this bug and found that if I deleted all my GNOME settings, the problem disappeared.

Sounds like it might be another grabs-related issue.

Status changed to 'Confirmed' because the bug affects multiple users.

I think this is close enough to bug 1181666 to be a duplicate. Plus comment #2 implies this bug should close anyway.

I'm having this problem years later in Gnome 3.36.3, Ubuntu 20.04.1. It also happened in 19.x. I don't think it's a duplicate of #1181666 because that states some interaction is still possible. In this issue, the whole ui is stuck. Windows, shell, clock, video that's playing, everything but the mouse cursor. Done a lot of searching for a newer ticket but none is a dead ringer like this.

The problem develops a while (hours?) after a fresh start and seems to get more exaggerated as time passes. On a larger scope, a fresh install is free of this problem at first, and then it develops after days/weeks of normal use. Had a hunch that it started after installing a particular package, but I can't remember what it was for the life of me. Clutter? Wxwidgets? Just a hunch anyway.

Closing of menus, tooltips, and to some degree open/save dialogs are delayed up to many seconds. This makes interacting with file managers and web pages infuriating. I have interface sounds on (smooth soundset, which includes menu actions) and noticed that opening a window menu and scrubbing the mouse over the other top level items (file, edit, etc.) still produces sound while this is going on, and the total wait time until the display unsticks is compounded with every one. ***To me this says it's not "no click" so much as "can't see".*** After zigging back and forth I can be waiting a minute or more, meanwhile I can still hear music playing, etc.

Regarding comment 2, I've not yet tried deleting my gnome settings because I didn't want to gum things up, but regardless I'm not sure how that implies this should be closed or is invalid. Gnome shouldn't be doing things to that file that interfere with its own operation, right? Again, this is from everyday use, and I've not been messing around in things.

Forgot to mention, menus in gnome-shell itself (top bar, dock, and other panels) do not suffer from this delay. They close immediately. This ticket is associated with gnome-shell, but the way the original author describes it, the shell isn't affected for them either: "This occurs in GNOME, GNOME applications and also for non-GNOME applications such as Firefox and Chrome."

This bug is closed. Please use bug 1181666 instead.

[Matt (mangoduck)]

Bug 1181666 does not at all describe the issue we are having here.
