I took a quick trace in Windows Canary (64.0.3254.1 (Official Build) canary SyzyASan (32-bit) (cohort: ASAN)), and I can't see anything particularly concerning in the trace - it all appears to be happening on the GPU, the main thread isn't doing any style or layout during the fade. @shrike - I see you marked this Mac only, do you know if the animation was happening on main thread or not? Can you grab a trace from your machine and upload it? @flackr, I've left the component as Blink>Animation, should these go to Internals>Compositing>CSS instead?
