Power Off dialog resets input and blinks one second after it's opened
Fedora 32, Wayland and XOrg, gnome-shell-3.36.4-1.fc32.x86_64, mutter-3.36.4-1.fc32.x86_64
Approximately 1 second after the Power Off dialog is displayed it blinks for one frame displaying something in red letters. Doing anything before the blink (pressing any button or selecting the "Install Updates" checkbox) has no effect (the checkbox is reset after the blink).
Steps to reproduce
- Open the Power Off dialog.
It seems to consistently reproduce after a reboot, on the second try and later what I'm seeing is no blink but the "seconds until power off" counter goes back and forth between 60 and some lower number.
Actually, when I tried opening the dialog a few times and cancelling, my system just powered off as if the counter was never reset on cancel...
What did you expect to happen
No blink, input handled correctly, the "seconds until power off" timer is disabled when I cancel the dialog.
