Comment 12 for bug 1576042

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.
