I've successfully compiled gtk3-engines-oxygen 1.4.1 but it couldn't solve my issue. Since Firefox 46 I have black borders around the navigation bar and search bar, in the bookmarks menu, and so on. Unfortunately, they are not fixed for me even with 1.4.1. Is that normal?
By the way, I'd like to correct the precious information Firas Kraïem gave us in his last comment about compiling from source. In step 1) you want to download this file https://launchpad.net/ubuntu/+archive/primary/+files/oxygen- gtk3_1.4.1.orig.tar.bz2 instead of the one mentioned in his post. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to oxygen-gtk3 in Ubuntu. https://bugs.launchpad.net/bugs/1576042 Title: Firefox 46 update causes theme errors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/oxygen-gtk3/+bug/1576042/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
