After a change something in a file, and move the cursor to a different line, the changed line is displayed with black background, until the file is saved.
I think this is a feature, to show which lines have been changed. The problem is that ALWAYS black is used for the changed lines, irrespective of the setting of the style configurator. This means that, if I use a style which uses black as foreground colour for certain syntactic elements, the text is written black on black!
Is there a way to explicitly set the background colour of a modified way - or at least, to switch off this feature?
