Resurrecting a much earlier workaround that we lost should help prevent the user-visible problems in the short term; I just sent a patch for that. I'm traveling, so I haven't seen any IRC discussion that may have happened recently, but I believe the CI regression we saw on that final two-step watermark patch are still unsolved. But since we've already reverted that patch, they shouldn't be blocking anything, right?
