this is failing on win* debug, I think the 17 failures in 1 day was catching up on older failures, but the rate is still worth looking at someting in the next 2 weeks.

All failures are Windows and Debug. Failure rate is frequent and consistent since about July 22. https://treeherder.mozilla.org/#/jobs?repo=autoland&filter-searchStr=windows%20debug%20browser-chrome&tochange=6c77cacaf82d169e8e7f557f2f14cae275f3410f&fromchange=4f240a4f635b71a641d45cd2c4d891600954edf3 suggests this started with the change for bug 1371000. :ng -- Please have a look.

Geoff, I will look into this today.

I believe I can reproduce this locally. Still investigating.

This is permafailing on Beta since the uplift on Wednesday.

Making notes here: Setup: Using a loaner a t-w864-ix via VNC at the default resolution of 1600x1200. Screen sharing slows the responsiveness of the Windows UI to crawl. Mouse inputs have a delay on the order of 10s. This begins as soon as the preview screen capture in gUM begins. Firefox remains at very low CPU utilization of ~3.5%, and the overall system load is also low at around ~12%.

Additional notes: Setup: as in comment 22, except that resolution is set to 1024x768. Screen sharing does not appreciably slow the responsiveness of the Windows UI.

Comment on attachment 8898394 [details] Bug 1383585 - add logs for device cache in VideoEngine; https://reviewboard.mozilla.org/r/169788/#review175032 Looks good, but something seems screwy with the way this is pushed to review, as it replaced the first patch instead of coming on top of it. If you re-push with one commit on top of the other, they should both appear in the review and the bug.

This patch doesn't meet the review requirements in MozReview for Autoland to push it. http://mozilla-version-control-tools.readthedocs.io/en/latest/mozreview/autoland.html#landing-commits

Both patches are discarded for some reason, and still separate review requests.

Make sure to push a new one with both patches. See http://mozilla-version-control-tools.readthedocs.io/en/latest/mozreview/commits.html#choosing-which-commits-to-submit
