Reproduced on LibO 3.4 on Mandriva 64 bit and Windows XP 32 bit
PS: When width greater then 0,75 then border not disappears but changes after reload, for examble 1.0 border becomes 1,5 border
Border looks strange if zoom of document is too small
Oops, hit <enter> accidently
Problem is [Reproducible] in all details with "LibreOffice 3.4.1RC1 – WIN7 Home Premium (64bit) German UI [OOO340m1 (Build:101)]".
Seems to be a fileopen problem, OOo 3.1.1 shows borders in LibO document (created due to original report) without problems.
Also other cell borders created with OOo 3.1.1 will not be shown in LibO, for example 2 lines different 5,05pt
Obsolete OOo 3.4-dev shows all borders without problems
Please feel free to reassign if it’s not your area
borders do not work as expected indeed
E.g. see also https://bugs.freedesktop.org/show_bug.cgi?id=37622#c33
I'll ping Cedric to see if this rings any bell for him. Cedric, assign this back to me if this is not related to your cell border work.

Created attachment 55618 [details]
An examle file with differnent border settings
The attached file contains the borders with the first 8 border style using different line width. (In the attached file the last part (9th border) is not set, so it is OK without borders in the file.)
In the file every border setting can be created two ways: set the border width first or set the line style first.
I've found the following problems:
Problem 1.: border style "None":
Border exists, if you set the line style to "none". The only way to erase borders is no unset the lines in the Line arrangement section on the left.
5th-8th border style (first double borders):
At 100% zoom levels the 1.0 and 1.5pt border width the horizontal and vertical lines are displayed (or magnified) differently. (Changing zoom levels you can notice similar problems on other cells: 0.75pt at 200%, 0,5pt at 300%.)
6th border style:
Borders are lost on 0.35pt and 0.5pt each way, and borders are lost if you set width first the 1, 1.1, 2.0, 5.0pt values and then the style.
7th border style:
borders are lost on 0.35, 0.75pt.
Ave also found that opening the attached file in IBM Lotus Symphony everything seems OK, all borders are exist.
But if I open (again) in LibreOffce (the borders are disappear) and resave it again the borders are truly lost.
I checked a bit more and it is the style:border-line-width property that confuses the importer. Investigating more now.
