Checking the latest build logs ( https://buildd.debian.org/status/fetch.php?pkg=mesa&arch=amd64&ver=18.1.6-1&stamp=1534235311&raw=0 ), I see the flag --enable-nine is not present. Judging by the performance of some games with Proton, I can assume Gallium Nine has indeed not been enabled. Could anyone confirm whether this bug needs to be reopened? Thank you.
