Authentication pop-up gets stuck if triggered just after suspending
Solus 4, GNOME 3.38
There are some cases where a GNOME Shell authentication pop-up appears attached to the top-left corner, without the possibility of closing or interacting with it until Shell is restarted (which means, until the user logs in again in Wayland).
I am unaware of what causes this precisely, likely a polkit dialog being requested while Shell is still inactive. Further investigation may be needed to replicate this more accurately.
