How to remove the highlighting bar when typing code in Netbeans 11?

Question

In Apache Netbeans 11.1, I use Nimbus and Netbeans light theme. This light theme has a problem that I find really annoying.

As shown in pictures below, when I type pub (for public) and stop half way, the row turns black, which makes the code not readable. If I finish the public keyword, the row will turn to a color set at Highlight Caret Row.

So how can I remove the black row when typing?

I found the answer. It's quite simple but I did not look up carefully. So here is the trick.

This black color bar comes from the Fixable Error of Annotations. So just changing the background of this Fixable Error category from dark color to any color will do the work. (Have to close and re-open the code editor to see the change) .

Here I changed to white background, and it's gone.
