+++ This bug was initially created as a clone of Bug #1498650 +++

I'm filing this as a placeholder bug for the next webrender update. I may be running a cron script [1] that does try pushes with webrender update attempts, so that we can track build/test breakages introduced by webrender on a rolling basis. This bug will hold the try push links as well as dependencies filed for those breakages, so that we have a better idea going into the update of what needs fixing. I might abort the cron job because once things get too far out of sync it's hard to fully automate fixing all the breakages.

When we are ready to actually land the update, we can rename this bug and use it for the update, and then file a new bug for the next "future update".

== Change summary for alert #16888 (as of Tue, 16 Oct 2018 16:53:51 GMT) ==

Improvements:

  6%  Heap Unclassified linux64-qr opt stylo     290,934,225.35 -> 274,569,644.29
  3%  Explicit Memory linux64-qr opt stylo       566,560,640.92 -> 552,296,146.98

For up to date results, see: https://treeherder.mozilla.org/perf.html#/alerts?id=16888
Interesting - the only thing significant in that sync is [1]. There's no corresponding drop on windows, and it's a 15MB drop in unclassified heap memory, so my best guess is that we're somehow eliminating a heap-allocation in the linux driver. Glenn, is that plausible?

I would be surprised if that change resulted in a memory reduction. It's possible, but unlikely. What were the other changes?
