[Bug 1876762] [NEW] gnome-panel becomes unresponsive

[roots]

Public bug reported:

Hi all,

I did a fresh install of Ubuntu 20.04 with gnome-flashback. However, after some time of usage the panel becomes unresponsive for both interaction with indicators & menus as well as editing the panel itself. Nevertheless, autohide is still working. 
I could not identify any triggering actions for this to happen yet. Logging out or rebooting will make the panel functional again.

1. $ lsb_release -rd
Description: Ubuntu 20.04 LTS
Release: 20.04

2.
$ apt-cache policy gnome-flashback
gnome-flashback:
  Installed: 3.36.1-1ubuntu1
  Candidate: 3.36.1-1ubuntu1
$ apt-cache policy gnome-panel
gnome-panel:
  Installed: 1:3.36.1-1ubuntu1
  Candidate: 1:3.36.1-1ubuntu1

3. Expected behaviour: The panel responds to mouse clicks on indicators
& menus.

4. Observed behaviour: The panel is unresponsive to any user
interaction.


If you need any further info for debugging, please let me know.

Cheers,
r.
