I have two machines {bubbles, murron} doing nightly dashboard builds of
VTK using nightly Mesa.

Each machine does a build of VTK using swrast and one with OSMesa.

Many tests pass on both machines when using OSMesa and fail on both
machines using swrast.

This is an example :

Test failing on bubbles and murron with swrast
http://open.cdash.org/testDetails.php?test=177420341&build=2813128
http://open.cdash.org/testDetails.php?test=177431601&build=2813212

Test passing on bubbles and murron with OSMesa
http://open.cdash.org/testDetails.php?test=177404326&build=2812997
http://open.cdash.org/testDetails.php?test=177411381&build=2813049

Many of the tests fail in a similar way: some of the elements of the
image are just missing.

Looks like lines, in particular, are missing. I don't see any recent changes to swrast/osmesa that would seem to cause this.

I think there's two approaches to narrowing this down:

1. You do a git-bisect of mesa to find the regression
2. Make an apitrace of the failing test so I can investigate.

Thanks.
