"Live" content shown on lock screen after suspend

[moritzheiber]

I have a weird artifact appearing on my screen when waking my laptop from suspend: The i3bar is showing, including "live", updating content on it:

(nevermind the misaligned UI login widget, I'll probably file a separate bug for that)

I cannot "interact" with the bar as far as I can tell, e.g. a click on an element does not trigger any UI actions, but it could potentially expose information to third parties that aren't otherwise allowed to use my laptop.

This does not happen if I simply "lock" my screen using a keyboard shortcut, it only happens when the computer is woken from suspend.

My expectation would be that the lock screen for waking from suspend doesn't expose any UI elements.

Yes, this is a long-standing issue and I believe it's due to a race between the lock screen and window manager.

Can you check if gnome-screensaver is installed, and if so, remove it, and log back in and see if the problem persists?

gnome-screensaver is not installed. This is a fresh 1.4 installation from the beginning of this week.

Most likely bug in gnome-flashback, please open upstream issue here - https://gitlab.gnome.org/GNOME/gnome-flashback/-/issues.

I'm closing this since this appears to be solved with the latest release of gnome-flashback on proposed Focal Fossa (3.36.3-0ubuntu1).

Thank you for verifying @moritzheiber !
