Description Alexis 2013-05-14 16:05:30 UTC
In Writer, dashed borders ( - - - ) in tables are not correctly displayed when the page is zommed out. The border becomes visible again if I zoom in.

It looks like a display aliasing issue.

Note that it's mainly visible on horizontal borders but. I guess that vertical ones also have the problem.

Plain borders are correctly displayed...

I had no issue with previous 3.6 versions.

PDF export is correct but this is a bit annoying when editing a document with invisible borders...

Please attach related files that show that problem & steps to reproduce it so others can clearly understand the issue.
Comment 2 Alexis 2013-05-16 07:18:24 UTC
To reproduce issue:

1. Create an empty document.
2. Insert a table with more than 2 rows/columns
3. Change all borders style to dashed one (use standard line width).
Table borders become invisible

Note 1 : it seems that double line borders have also similar behavior
Note 2 : It also looks like very large borders become visible

Suggestion for developers: If the displayed line should be < 1 pixel due to zooming, it should be at least 1 pixel large so that stays visible. This is what seems to be done with standard plain borders

Reproduced on LO (Win7 Home Premium 32bit), but I see missing (not invisible) horizontal line(s)
-> confirm missing with Page Preview & export as PDF

I think it's a problem with line width that is too thin by default, as on Calc. This problem not occur if I set line width above 1pt.

Reproduced with LibO on Win7.

Created attachment 88065 [details]
dashed border table sampe

reproduced with under Win7 64bit.
see attached file. dashed borders look invisible and they are partially visible only at some high zoom levels.

Linux and Mac users are encouraged to test this bug since it has only been reported by Windows users until now.

I add Writed expert to CC list.
