buggy PDF export

Exporting a white filled circle/ellipse with an outline results in small artefacts in the top left and the bottom right corner of the circle 

Steps to Reproduce:
1) draw a circle in Draw/Writer/Impress
2) change the filling to white
3) increse line width (the wider the line the longer the artefacts seem to become)
4) Export to pdf

Actual Results:
small artefacts as seen in the attachment

Hardware:
Win 7 Enterprise Version 6.1 build 7601

I can see dots in the places you describe when opening attachment 114815 [details] in Firefox 37 on Windows, but not on Ubuntu.
SumatraPDF, Foxit or Evince don't show anything.
Importing to Inkscape doesn't show anything.
NitroPDF 8 shows vertical lines in place of the dots. This is true also for a PDF exported using LibO 3.6.7.

In what software did you see the artefacts?

Win 7 Pro 64-bit, Version: 4.4.2.2
Build ID: c4c7d32d0d49397cad38d62472b0bc8acff48dd6
Locale: fi_FI

Ubuntu 14.10 64-bit
Version 3.6.7.2 (Build ID: e183d5b)
Comment 3 Christian Pietzsch 2015-04-18 14:38:19 UTC
I noticed the problem in Foxit Reader (latest version) on Windows 7.
I tested it now with PDF Reader on Android (no artefacts) and Firefox 37.0.1 internal PDF reader under Win 7 (see attachment). With Adobe Reader XI there are also no artefacts.

Cheers
Christian

Forgot to mention that the artefacts don't appear on printouts of these pdf.

I see artefacts in Foxit Reader 5.4 but no artifact with Adobe Acrobat 7

so I wonder if this is really a LibO bug or a bug of the specific PDF reader...

P.S. please Christian, next time do not change the version field to the latest version you see a bug... it must indicate the earliest release the bug appeared.
Comment 9 Christian Pietzsch 2015-08-20 14:41:27 UTC
Sry misunderstood the thing with the version number
The problem is that these artifacts appear in most of the PDF readers. I did a quick test in Chrome 44 and you can see the artifacts too. (looks equal to foxit reader)
Only two (Adobe/nitro) out of 5 (Firfox/Chrome/Foxit) PDF reader show no artifacts.

Tested again in Version:

Version: 5.2.1.2
Build-ID: 5.2.1-2
CPU-Threads: 4; BS-Version: Linux 4.4; UI-Render: Standard; 
Gebietsschema: de-DE (de_DE.UTF-8); Calc: group

Operating System: Manjaro Linux 16.08 64-bit

Seems like it has been fixed. I exported the pdf on the system discribed abouve and opened it on different applications and operating systems (Windows 8/Linx)(Firefox/Windows 8 PDF Viewer/Evince/GIMP/Foxit Reader 2.1.0805)
