The chromium snap is built on xenial (16.04), and not against the gnome-3-26 backports PPA (https://launchpad.net/~ubuntu- desktop/+archive/ubuntu/gnome-3-26/+packages).
This means that the snap builds against version 3.18 of GTK, which is older than what the gtk-common-themes snap supports (>= 3.20). As a result, the snap isn’t looking for the current theme's gtk.css under $SNAP/data-dir/themes. Building against a newer version of GTK would solve the problem. As an experiment, I rebuilt the stable snap against core18, on bionic, and verified that the issue went away. Core18 is not ready for general use though, there are other issues (among others, lack of support for xdg-open). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1791307 Title: [snap] GTK theme doesn't match the host system Status in chromium-browser package in Ubuntu: Triaged Bug description: The GTK theme of the chrome and file open/save dialogs doesn't match the theme on the host system.
