description |
The new About screen for upcoming Inkscape 0.92 exposes a long-standing issue in Inkscape's cairo-based renderer with cairo >= 1.12.4. Thin lines disappear completely when zooming out, or down-scaling such objects (e.g. as group).
Steps to reproduce:
A) with current RC 0.92pre4 build:
1) launch inkscape
2) open 'Help > About Inkscape'
3) shrink the size of the About dialog
B) with any Inkscape build >= 0.91:
1) download about.svg from repo [1]
2) open 'about.svg' in Inkscape
3) zoom out repeatedly
The smaller the overall output of the line-art drawing, the more it may change appearance because thin lines disappear.
Inkscape's cairo-based renderer does not expose the same issue with older versions of cairo <= 1.12.2 (see attached screenshots with a slightly older trunk build).
Reproduced with Inkscape 0.92.x r15275 and cairo 1.14.6, 1.15.5 (git master) on OS X 10.7.5.
=====
Likely related issue:
Bug #1174909 “inkscape fails to print thin lines to PDF”
(not fixed with latest cairo from git master)
