This crash signature also has non-WebRender reports: 56.0.2, 57 beta, 58 beta, 59 alpha. Is this related to ANGLE or something for "Core > Audio/Video: Playback"? Some background: > Has dual GPUs.

Instead it is done before the decoder is started. (Ritu Kothari (:ritu) from bug 1274132 comment 14) > Disable D3D11 for some device drivers, this code stabilized on Aurora over the weekend, Beta47+

None of the crashes in the last 6 months were with WR enabled. Booting this bug out of WebRender.
