[opensuse] howto change icon's text fonts?

Hello, Since some time on my Leap 15.0, the text is blurred by some background shadow like you can see on this screenshot: https://www.cjoint.com/doc/19_07/IGyf5XkN47k_Screenshot-20190724-075730.png I don't know if it's an update or some error of mine, but how can I change these fonts? thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
