#846 Doesn't follow my qt5ct theme consistently

[burak]

qmmp-1.0.6-3, on Arch (Fluxbox) system with qt5ct managing the system-wide (qt) theme, launches with the white playlist window instead of the system color. Everytime I need to uncheck and check again the "Use system color" setting. I use "Simple User ınterface" of qmmp. Launching from terminal produces this:
