Underlined text highlighted

After selecting areas for redaction in 'Writer' and then click on OK the Draw module launches showing previews of redacted text but it also shows unintended underlined text being highlighted.
This happens whether the underlining was created in Word or Writer. It also happens whether the file is in odt or docx format.

Please attach the original .odt document so that we can check there is no unexpected configuration in the formatting/styling.

Steps:
1. Open attachment 186917 [details]
2. Tools - Redact
3. In the Draw instance, draw a filled rectangle covering the content
4. Right-click rectangle - Arrange - Send to back

Now you see the white background for the underlined text.

Redaction was introduced in 6.3 and I see this already in 6.3 bibisect repo.

The white background appears over underlined text as soon as Draw launches after selecting Tools>Redact in Writer. This happens before text or block areas for redaction have been selected.
Thre is no need to "draw a filled rectangle covering the content" as stated in step 3.
It seems that the Draw module is 'seeing' underlined text as highlighted.

Yes there is a need. As the background is white otherwise, how am I going to see that the underlined parts have a white bg?
Comment 7 Ken 2023-05-11 14:36:34 UTC
My comments are written from a user's point of view and maybe your comments are written from a program writer's perspective? This may be where the difference arises?

All I know is that I do not need to draw a rectangle. I simply open the document in Writer and go to Redact it and then the Draw module launches. At this point any underlined text is immediately highlighted without my input.

I hope this clarifies what I mean.

Thank you.
Comment 8 Ken 2023-05-11 17:07:35 UTC
I have discovered why I see the highlighting of unerlined text when the Draw module launches: -

It is because I have the "Document background" color set to a non-white colour.
If I stay with the default "White" RGB color of 255 255 255 then all is okay. I see no highlighting, but that does not mean it is not there. It justs blends-in with the white background.

My customised "Document background" RGB color is 200 210 200 which is a pale grey/green and this causes the "white" highlighting to stand out.

To allow for customised "Document background" colors the highlighting should not happen at all.

I hope this helps with fixing the bug.

Thank you.
