Comment 0 for bug 1719106

After upgrading my Ubuntu GNOME 17.04 system to Ubuntu 17.10 the notification message window colour is unreadable.

It is black text on very dark grey background. See attached screenshot.

To make sure that it does not come from my settings, I created a new user account with empty home directory and logged in using that user account. The issue still remains.

I am not sure if the notification messages are produced by the gnome-shell package.
