Details
Off-screen animation throttling causes considerable stuttering in the 3D transforms demo: https://keithclark.co.uk/labs/css-fps/nojs/
For whatever reason, this is more noticeable on Windows. On MacOS, the stuttering starts in the middle of the second "scene".
Profile of throttling happening at around seven second mark: https://perfht.ml/2PLUy2W
Setting pref dom.animations.offscreen-throttling;false makes the stuttering go away.

This might be related to Bug 779598 (i.e. we cannot run preserve-3d off the main thread).

Unfortunately, Bug 779598 doesn't help. We still have to find the root cause. Maybe we can tweak some for offscreen throttling stuff for cases like this.
