Prerequisites

• [X] I performed a cursory search of the issue tracker to avoid opening a duplicate issue.

Checklist to make sure the issue is not on your end

• [X] I have made sure that I do not have multiple versions of the theme installed. Only one version should be installed in either ~/.local/share/themes or /usr/share/themes or ~/.themes
• [X] The file ~/.config/gtk-3.0/gtk.css does not exist. (If it does, backup and remove it.)
• [X] I have logged out and in again.
• [ ] Dark theme only. I have enabled adw-gtk3-dark in gnome-tweaks AND set the appearance to dark in gnome-control-center
• [ ] The flatpak theme is installed org.gtk.Gtk3theme.adw-gtk3 and org.gtk.Gtk3theme.adw-gtk3-dark
• [ ] The app I'm having an issue with is an actual GTK3 app and is not coded using another toolkit like GTK2, GTK4, QT, etc.
• [X] I have created a new user profile without any modifications except adw-gtk3.

Description

Chrome's title bar or address bar may appear slightly shorter when using fractional scaling (Wayland). This seems to be related to the window size, as it's possible to precisely align the right edge of the window during resizing.

I believe this is a Chrome bug rather than an issue with the theme. Upon further investigation, I discovered that the default Adwaita theme exhibits the same problem at various fractional scaling levels.
