Bad and good visualizations
When fixing Bug 37246, I have found that test PDF contains unneeded strokes with incorrect colors.
Investigation of this bug led me to commit
and to Bug #109708 from OpenOffice:
I've tried to remove this commit and see what happens.
Surprisingly, existing negative effects were gone, while new ones was not appearing.
In comments to Bug #109708 we can find out that more correct solution to problem is to "Change the way of displaying objects"
Which exactly, I suppose, was done.
Problematic and normal rendering you can see at attached image.
Both PDF used for testing are also attached.
