Hmm I guess we'd need to drop the draw call somewhere (since results are unspecified). Not sure where the optimal place to do it is. Or invoke out-of-bounds behavior somewhere else. I think llvmpipe (which we care about a lot more than softpipe in general) already does this. mesa: 52b73caaf40e79c90a105ec6d349abb3398e3c6b (master 17.3.0-devel) gl-3.1-vao-broken-attrib still crashes on softpipe. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
