Created attachment 185394 [details] Redaction in okular Open a pdf document, then open the annotation tools. Choose "Draw a straight line", press "Advanced settings for selected tool", set width to 6 (for example). Then draw a line to redact some text. See "Redaction in okular" image to see the result. Then, save the pdf and open it with Firefox, for example. On second image, you'll see that the drawed lines do not redact the text (they have different width).
Created attachment 185395 [details] Same pdf but seen in Firefox As you can see, the redaction is not working.
There's no redaction, this is strike-trought, the text is still under it and can be selected and copy and pasted. Please attach the document that has this problem.
