System -> Application Appearance -> Colors -> Colors (tab) -> Button Background 2. Change Color Actual Results: No changes Expected Results: Changes Picture of the Problem: https://launchpadlibrarian.net/161472081/muonD-bBg.png
Known problem, I hope I'll be able to solve this together with the port to Qt5.
Works now, using a different technology to render the buttons.
