Description Harald Koester 2012-02-16 09:25:48 UTC
Problem description: 

[1] Open new text document.
[2] Display Non-printing Characters.
[3] Insert some empty paragraphs.
[4] Insert a line break (Shift+Enter).
[5] Scroll down document until the first empty paragraph is no longer visible.
[6] Change the alignment of the last paragraph to right-aligned. The characters for “Line Break” and “End of Paragraph” are no longer visible. Expected: Visible at the end of the line !!
[7] Scroll down document until the last paragraph is above the working area and scroll back again.(first paragraph still above working area) Now the missed characters are visible.
[8] Change the alignment back to left-aligned: Now both characters are visible twice, at the beginning and at the end of the line. Expected: Visible only at the beginning of the line !!

If you format your page with 2 columns, the bug exists for both. By the way: If there is no space between columns, right aligned non-printing characters of the left column are visible not at all. Also a bug?

Bug already exists similar in Version 3.4.x.

As of LibreOffice 3.5.1.2 (Build ID: dc9775d-05ecbee-0851ad3-1586698-727bf66) you can't get any non-printing characters to be displayed.

This worked in a previous release I used. I always use this function, so this is annoying.
Comment 2 sasha.libreoffice 2012-05-21 05:03:25 UTC
Thanks for bugreport
I am not sure that it is the same bug, but reproducible in 3.5.3 on Fedora 64 bit
Steps to reproduce:
0. Open new text document.
1. Display Non-printing Characters.
2. Press Ctrl-R
Expected: end-of-paragraph remains visible
Actually: disappears. But appears after adding new paragraph or scrolling page
Comment 3 Patrik Nilsson 2012-05-22 02:04:59 UTC
I use Debian 6.0.4 and after upgrading Libreoffice this function is completely gone visually. The button and menu settings still are there, but I have never seen any effect of them, not even for a blink of an eye (i.e. during redraw).

Sasha: I can't reproduce your effect at all.
Comment 4 sasha.libreoffice 2012-05-22 03:32:20 UTC
@ Patrik Nilsson
As I can understand:
1. Bug from comment 2 not reproducible
2. Bug from initial description still exist
I right understand or no?
Comment 5 Patrik Nilsson 2012-05-22 03:45:51 UTC
Sasha:

1) Bug from 2 can't be reproduced on Debian.
2) The initial bug still exists and got worse in the latest release. Now *no* non-printing characters are displayed.
Comment 6 sasha.libreoffice 2012-05-22 04:22:55 UTC
May be because of difference in Video and desktop. In my case it is Intel and KDE, also Windows 7 with Intel video.
Comment 7 Harald Koester 2012-06-23 09:45:34 UTC
Bug of comment 2 reproducible with Win 7 and LO 3.5.3.2.
Comment 8 Alexandr 2014-07-14 18:25:34 UTC
I reproduce both initial bug and comment 2 with LibreOffice 4.3.0.2 on Debian Jessie x86_64.
I belive this issue does not make work really harder in most cases, because the nonprinting characters return to normal state after scrolling. Hence I decrease severity.
