With an inverted system color setup (white text on dark background) the Jira interface is hard to use because input fields have a text color set but not a background color (see attachment).
I can hardly see the text because the Jira CSS defines dark text and my desktop defines the dark background.

Please add a background color (e.g. #fff) to superbatch/css/batch.css,
selector "form.aui .text, form.aui .password, ..."
