Some text is black on black, so not to be seen. Probably not intended like this.
The black-on-black text is usually not relevant. Text that has been modified, added, or removed shouldn’t be black and I’m quite sure it isn’t.
Yes, but it is hard to see the context, so judging if it is a false or a true positive is hard. So I disagree on the relevance. Black on gray would be okay.
As a workaround, you can select text to make it visible. As we’re planning to rewrite the whole process anyway, I’m not going to make small fixes to the current code anymore.
