Details
When I visit https://tyk.io/ without webrender enabled, it renders in a few seconds. When I visit https://tyk.io/ with webrender enabled, Firefox locks up for about 40 seconds and it's cpu utilization tops 600%. Profile with render disabled: https://perfht.ml/2Cps4HA Profile with webrender enabled: https://perfht.ml/2Cq1kXB I'm using Firefox Nightly on OS X on a Macbook Pro.

I somehow cannot repro on a clean profile with WR enabled, but can repro with my personal profile. Here's a perf profile: https://perfht.ml/2V5tBts Looks like we're rasterizing blobs over and over?

This page isn't amazing on Win Nvidia but is good enough to ship.

Brian can you add the "Renderer" and "RenderBackend" threads to the profiler and capture a new profile of the hang?

Ok. This profile is waiting for Blob image rasterization. Can you add "WrWorker" to custom threads by name configuration of the profiler and grab a new profile?

I had to increase my profiler buffer size to grab this. Here you go: https://perfht.ml/2TAmXu0

It looks like we're spending a lot of time copy some large images. I wonder why it's not reproducible for everyone.

Is this still reproducible? Here is an archive of the site close to the time of reporting if you need it.

Redirect a needinfo that is pending on an inactive user to the triage owner.
:gw, since the bug has high priority and recent activity, could you have a look please?

This renders fine on my local machine, but I wonder if it's related to bug #1767570.

This seems to work well after https://bugzilla.mozilla.org/show_bug.cgi?id=1767570 landed.
