Description Roeland 2016-04-09 20:50:22 UTC
Created attachment 124210 [details]
document with the problem

In the attached document cells D19 to D28 have a border line on their right side. The cells with the numbers 1-4 have a width of 0,75 pt the cells with numbers 5-10 have with 0,05pt. However, the line is shown as the same thickness. If I print this document the difference is there (dfferent thickness of the borders).

This is confusing behavior, as I expect to have the same result on my screen as when printing a document.

Hi Roeland,

Thanks for filing the issue.
Looking at bug 79787, and especially the explanation in a related commit
  https://cgit.freedesktop.org/libreoffice/core/commit/?id=51737960911d41593ffd9792a6a85aeaa86824fd
it looks to me as if your report can be marked as as duplicate..
Can you please check if that is OK?

Regards - Cor

Hi Cor, I'm not really sure about this, the problem is ocurring in a ods file I'm currently using.

It might be that this problem originates from a docx document, or was round tripped once, but I can't remember if this is true. What makes you think this is the same problem?

By taking a closer look the bug might indeed be related. You can close it as a duplicate, I will retest this onces the other issue is fixed.

Ah sorry, I missed that.

No it is not related I see now.
I confirm the problem (and will look for existing issues on this subject.. )

that I do not see... hmm.
Comment 8 Roeland 2016-04-12 17:36:05 UTC
Actually the issue is more easy to reproduce than I thought.
I guess this will be more like an improvement request than a bug report:

Steps to reproduce:

*select some cells in calc, then rightclick and chose "format cells".
*create some lines around some cells with 0.05pt, then take a small part of those lines with 0.75
*result: although the thickness of the lines isn't the same, they look exactly the same in Calc. The difference is noticable when printing though (see attachment).

So, 
* or this is a printing issue
* or this is no issue, and I would like to propose to improve this situation so that differences in thickness can be visually noted

Not confirmed

I can not represent the bug. 
Laptop resolution is 1366x768 and when the calc sheet is on 100% every border looks the same no matter the thickness.
When zoomed in at over 180% one can see the differences in border thickness.

Tested with version:
- 5.4.3.2 (x64)
- 6.0.0.0.beta2 (x64)
Windows 10 64
Locale: bg-BG (bg_BG)

Thanks for testing Chavdar.

Closing as notabug. It's just a matter of screen resolution.

On my system, setting zoom to ~250%, shows the difference of 0.75 pt
and setting zoom to ~310%, shows the difference of 0.50 pt
