System information

SolveSpace version: 3.0~fd2dfe87

Operating system: Fedora 31

Expected behavior

Model should display with no red edges.

Actual behavior

Model has red edges, or even stray red segments.

Additional information

When the 8 circles cut into the center hole or sometimes the outer ring, these red edges appear. Analyze indicates no naked edges. I'm opening this issue to document it before submitting a PR that was not intended to fix it but does.
