Created attachment 32732 [details]
shows hardware rendering of the same data--no artefacts
notes: zooming in the artefacts recede toward the edges of the tubes, but never go away completely. the thickness of the tubes are 0.075, some but not all of the affected tubes are overlapping or very close to their neighbors. Turns out this is not a bug in Mesa, actually we're using OSMesa and the default depth buffer is only 16 bits. So we just have to explicitly set it to 32. |

Created attachment 32731 [details] shows artifacts appearing on on rendered surfaces When rendering a certain set of stream tubes I see artefacts on the surfaces of the tubes. Both mesa 7.5.1 and Mesa 7.7 exhibit. It doesn't happen when using hardware rendering. see that attached images
