I posted a more complete patch (also removing the now unused local i) for this in https://lists.freedesktop.org/archives/dri-devel/2017-December/161116.html . I'd like to only apply this once the problem discussed in that thread is fixed though, but unfortunately the other patch I attached there doesn't seem to fix it. What's the current plan for fixing this issue?
