+++ This bug was initially created as a clone of Bug #1491130 +++ 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".

Pushed by jmuizelaar@mozilla.com: https://hg.mozilla.org/integration/mozilla-inbound/rev/153d6dc38962 Update webrender to commit 6fa046c936b9d720726d27c3b0514ee66a305b69 https://hg.mozilla.org/integration/mozilla-inbound/rev/432d22af68c8 Replace BorderWidths with LayoutSideOffsets.

Backed out for failing awsy\test_memory_usage.py Push that started the failures: https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&resultStatus=testfailed,busted,exception&classifiedState=unclassified&selectedJob=199991961&revision=432d22af68c825eebd86482c714b3cffcba408c7 Failure log: https://treeherder.mozilla.org/logviewer.html#?job_id=199991961&repo=mozilla-inbound&lineNumber=2286 Backout: https://hg.mozilla.org/integration/mozilla-inbound/rev/911c7836b359cfa31f82e8f90e411e4c9709ade7

The test is failing because heap-unclassified is negative. Usually that means bogus memory reporting. WebRender memory reports shouldn't be running at all on non-WR jobs like the failing one, but if they were, but it is somewhat suspicious given that we recently added reporters for WR. Unfortunately, the assertion seems to prevent uploading of the memory reports as artifacts. I've done a try push with the assertion disabled, so that we can hopefully access the reports: https://treeherder.mozilla.org/#/jobs?repo=try&revision=0fc210a6a72b5938c11d7f0a6382e1a7720f3cf7

Relanded this since it was not the culprit for the above mentioned issue. I apologize for the confusion, the real culprit was Bug 1491395.
