Here's a patch to fix this. (generated against source obtained from "apt-get source ubuntu-themes").
I'm hoping someone here can take this & land it. Please let me know if there's anything else that's needed here. Thanks! ** Patch added: "patch" https://bugs.launchpad.net/ubuntu/+source/ubuntu-themes/+bug/1478173/+attachment/4433788/+files/theme-patch.patch -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-themes in Ubuntu. https://bugs.launchpad.net/bugs/1478173 Title: Ambiance & Radiance themes are missing a "background-color" for tooltip elements (needed for GTK3-enabled Firefox Nightly) Status in ubuntu-themes package in Ubuntu: New Bug description: Firefox Nightlies recently became GTK3-enabled, and that uncovered an issue with Ubuntu's Ambiance & Radiance GTK3 themes. They're missing a "background-color" for the .tooltip {...} CSS rule in their config files. They have a "tooltip_bg_color" variable, which they use to set up a background-image (really a gradient), but there's no background-color. This causes problems for GTK3-enabled Firefox, because it reads back some system-colors by setting up a dummy tooltip and reading the (currently-not-useful) background-color and the foreground-color. Right now, this produces unreadable output (for the user) with white-text-on-a-white-background, as shown in this screenshot: https://bug1187203.bmoattachments.org/attachment.cgi?id=8638351 The solution is simple -- just add this one line to the ".tooltip" CSS rule in gtk-widgets.css: background-color: @tooltip_bg_color; For more details, see bug https://bugzilla.mozilla.org/show_bug.cgi?id=1187203 ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: light-themes 14.04+15.04.20150410-0ubuntu1 ProcVersionSignature: Ubuntu 3.19.0-23.24-generic 3.19.8-ckt2 Uname: Linux 3.19.0-23-generic x86_64 ApportVersion: 2.17.2-0ubuntu1.1 Architecture: amd64 CurrentDesktop: GNOME Date: Fri Jul 24 17:35:25 2015 EcryptfsInUse: Yes InstallationDate: Installed on 2015-05-18 (67 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) PackageArchitecture: all SourcePackage: ubuntu-themes UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-themes/+bug/1478173/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
