Frequent bug: while sorting by y-coordinate, the vertices are sorted, but the data coming with the vertices is not.
Gouraud shading, forgot to sort intensities

In my case I was calculating a barycentric coordinate of one vertex and assigning it to a different vertex by mistake.
The artifacts looked exactly the same as you presented, if it is the same problem then the description could be more informative.

It's probably left over from a previous version where scanline was used for rasterizing triangles.
