Description Ilya Zubakin 2018-02-11 08:38:10 UTC
When I change the scale of the document there are several artifacts with cells borders. Borders are going through next cell border.

Steps to Reproduce:
1. Open this document
2. Change the scale.

Actual Results:  
On this picture, you can see that lines a go through neighbor cell borders
The same result exists in a printing preview dialog.

Expected Results:
Check the scaling algorithm. I think now it's not properly calculated the end of current cell or border length. 

Reproducible: Always

User Profile Reset: Yes

Additional Info:
It happens in a new release.

I reproduce this on release.
Build ID:60bfb1526849283ce2491346ed2aa51c465abfe6
CPU 线程:4; 操作系统:Linux 4.14; UI 渲染:默认; VCL: gtk2; 
区域语言:zh-CN (zh_CN.UTF-8); Calc: group

It works in:
Build ID: 9feb7f7039a3b59974cbf266922177e961a52dd1
CPU threads: 4; OS: Linux 4.14; UI render: default; VCL: gtk3; 
Locale: zh-CN (zh_CN.UTF-8); Calc: group

I also noticed that, if I set the zoom level below 280%, there are artifacts. But if the zoom level is 310% or above, the artifacts to the right of column CQ are gone, but artifacts on column CX remain.

I also did a real printing-out of the page, and find that the borders are OK, without artifacts.

I am adding Armin Le Grand to cc list, as he has worked on a series of improvements on the cell borders. 

@Armin Le Grand: If you need me to to some bibisects, please let me know.

borderline: first versionj with line end adaptions
Added usage of defined extensions to the BorderLinePrimitive,
also added a first version to detect all cuts with adjacent
borders and produce the correct extensions, for single and
double lines. Not completely happy with it, but a first

Comment 9 Armin Le Grand 2018-10-27 17:12:31 UTC
More or less gone with latest changes in master. Only slightly too ong lines when far zoomed out, as result of AA paint, but not really bad from my POV. Same rendering when save as PDF and view with a PDF renderer, so not sure if it has to do with LO
