My Top bar config:

   topBar: {
        title: {
          text: 'Home',
        },
        searchBar: true,
        searchBarPlaceholder: 'Search',
        largeTitle: {
          visible: true,
          fontSize: 30,
          color: 'white',
          fontFamily: 'Helvetica',
        },
      },

Demo:

I was wonder whether because my MacOS is in dark theme, I changed my MacOS to light theme but the problem still happens

Figure out myself by adding option drawBehind: true, to the topBar
