Theme autodetect not working

[T3sT3ro]

I'm on ubuntu 22.04 with dark OS settings and I just installed the 0.13.3-2-all.deb version of the package, and the theme auto-detection didn't work. The tray icon used black variant instead of white on a black taskbar, making it invisible. I changed the icon theme manually so it's a minor thing, but I was confused in the beginning, not sure if program crashed on startup because I didn't see the icon :sweat_smile:. The settings window also used light theme when auto-detect was set.
