1 year ago I've added a small test to show the issue.
Just make a new family tree and import the attached .gramps file (GitHub didn't accept that file ending so I added .txt, just remove it).
Also, here are some screenshots of the test.
Note that I've set "View" to "All relatives".
Gramps file topola-viewer-119.gramps.txt
As Brother
As Mother
As Half-Brother

When not all of the parents are shared, the siblings are not rendered. To reproduce, create Brother, Sister, Half-Brother, Father, and Mother. Select Brother and add the parents, Father and Mother. Add Sister as a sibling. Select Half-Brother and add the parent, Mother, and leave father unknown. When looking at the graph for Brother, Half-Brother is not rendered (even with All Relatives).
