Graphics artifacts in planarity

[Edward Cherlin]

Binary package hint: gplanarity

Ubuntu 10.10 Meerkat
gplanarity 16723-1

Normally gplanarity displays blue points outlined in black, and gray lines connecting the points. I have been getting various extra gray areas, usually triangles but sometimes spurious lines in gray on white or white on gray. Example attached with several triangles. The spurious markings change on almost every move.

Reinstalling fixed the problem.

Nope. I wrote too soon. The problem is back on the next level.
