I am new to Manjaro and KDE (previously Ubuntu, Gnome and macOS user). I have a solo Linux install (no dual boot and wiped the hard drive) on 2009 MacBookPro with SSD. I have tried several dozen KDE dark and light themes. Many system setting windows present with black text on the charcoal/brown window background (the default Konsole color). I cannot find the setting to fix this contrast problem. It is not present in every app or window, but I always have the problem in Settings > Appearance > Global Themes. Otherwise, Manjaro works well as long as I stick to standard apps and don’ t customize too much. The drivers I need are there, and the repositories are great.
