Description hubertus 2012-01-23 10:38:58 UTC
Variation of line thickness 0,25 to 1.0 for a table does not show any effect on video display. This makes it impossible to control ongoing work without having it printed out.
Comment 1 sasha.libreoffice 2012-05-11 00:20:41 UTC
Thanks for bugreport
Currently difference between them can be seen only if seriously zoom sheet.
If use Print Preview, we can see the same problem, some lines often sisappears depending of zoom and thickness.

reproduced in 3.3.4 and 3.5.3 on Fedora 64 bit
in 3.3.4 difference in thickness not seen even if zoom. So, improvement in this direction done.

Changing version to 3.3.4 as most early reproducible

Confirmed with:
LO 3.5.5.3 
Build ID: own W7 debug build
Windows 7 Professional SP1 64 bit

Difference between 0,05 and 1,00 borders is clearly visible but 0,05;0,15;0,25 stepping could be unnoticeable on display (sometimes big zoom is required).
Comment 3 khagaroth 2012-07-27 22:14:54 UTC
This is a very annoying behavior and it is a regression compared to OOo, I didn't test the recent OOo (AOO), but it worked in older versions. It gets much worse with antialiasing enabled in options. It is absolutely impossible to visually format a table because of this bug.
Up to 125% zoom the thickness is completely indistinguishable. 0.05 up to 0.39 look absolutely identical, on the other hand adding one pt to 0.40 is causing an extreme thickness jump and then it is the same again up to 1.49 and another extreme thickness jump for 1.50 and so on.
There are also some other issues with border rendering, that might be related, for example left and right borders get rendered too thin (top and bottom render correctly).
Comment 4 sasha.libreoffice 2012-08-02 05:44:50 UTC
Thanks for additional testing.
"Version" is most old version where bug appears. Not current version.
Changing back to 3.3.4
