The default sizing for user-icon style was not defined in the theme, but it simply used the default Avatar iconSize from UserWidget.js. This didn't work with the current fallback avatar styling (i.e. when the avatar icon is not set for an user account, and a symbolic icon is displayed in its place), as the fallback StIcon was not scaled to align inside the circle shaped user-icon properly. Define the user-icon and corrected fallback StIcon sizes in the stylesheet to correct this. The default 64px user-icon size is based on default UserWidget.Avatar iconSize. The sizing for the StIcon is taken from `.user-widget.horizontal .user-icon` styling, which uses the same base icon-size. Additionally, the special `.user-widget.horizontal .user-icon` styling is removed, as it is now redundant. Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1490> |

Summary
Do not edit the CSS directly, edit the source SCSS files and the CSS files will be generated automatically when building with meson + ninja and left inside the build directory to be incorporated into the gresource XML (you'll need to have sassc installed).
How to tweak the theme
Adwaita is a complex theme, so to keep it maintainable it's written and processed in SASS, the generated CSS is then transformed into a gresource file during gtk build and used at runtime in a non-legible or editable form.
It is very likely your change will happen in the _common.scss file. That's where all the widget selectors are defined. Here's a rundown of the "supporting" stylesheets, that are unlikely to be the right place for a drive by stylesheet fix:
| File | Description |
|---|---|
| _colors.scss | global color definitions. We keep the number of defined colors to a necessary minimum, most colors are derived from a handful of basics. It is an exact copy of the gtk+ counterpart. Light theme is used for the classic theme and dark is for GNOME3 shell default. |
| _drawing.scss | drawing helper mixings/functions to allow easier definition of widget drawing under specific context. This is why Adwaita isn't 15000 LOC. |
| _common.scss | actual definitions of style for each widget. This is where you are likely to add/remove your changes. |
You can read about SASS on its web page. Once you make your changes to the _common.scss file, you can run ninja to generate the final CSS files.
