It looks like this is a gnome-shell bug revealed by one of the many extensions you have installed.
But I don't think it's a bug in any extension. It should be fixable in gnome-shell. Please report the bug upstream here: https://gitlab.gnome.org/GNOME/gnome-shell/issues and then tell us the new bug ID. ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => Low ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1820775 Title: gnome-shell's user menu/item is not aligned like other menu items Status in gnome-shell package in Ubuntu: Incomplete Bug description: I just noticed that the user menu of gnome-shell is not aligned like other menu items. When clicking it, it shows an extended box too. I expect it to be like other menu items. Note that I'm using Default as my gnome-shell user css, but other css'es also show this bug.
