Compositor Is None

about:telemetry incorrectly reports gfx.features.compositor as none (under Environment Data/System).

This is caused by NotifyCompositorCreated not firing at [1]. In my testing, mWindowType is always `eWindowType_child`.

E10s is disabled.

Might be skewing your telemetry data results.

Looks like a bug, thanks. Luckily it shouldn't skew our results since we only graph Windows compositors, and this bug looks OS X specific.
