The problem boils down to computing t = -2.e8 / (-2.e8 - 3.5) We wind up with t=1, but t should instead be some value very close to, but less than 1.0. Tried double precision with no change. Will have to study this further someday. Brian Paul Do you still experience this issue with newer soft ? Please check the status of your issue. Unfortunately, swrast, softpipe and llvmpipe all still suffer from this. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
