Yes, It's 'Apple'

Here's a trace file I ran using Xcode's profiler, it occurs at 45 to 60 seconds.
Seems the major CPU usage has nothing to do with MacGesture, but a problem with macOS, A higher mouse polling rate is likely to cause the problem (mine is 1000hz)

I've changed the polling rate to 125hz, and the CPU usage is reduced to ~5%
