Arrows sometimes stutter

Hello,

Firstly, this is *awesome.* Really one hell of a great beta you have here for what looks to be a superb rhythm game that could garner quite a following.

During gameplay, sometimes arrows stutter, which really throws me off. Is there any way to fix this? Is it a known bug? The game runs at a constant 60FPS in my Chrome browser.

Here are my specifications:

Processor: 2.6 GHz Intel Core i7
Memory: 16 GB 1600 MHz DDR3
Mac OS X 10.9.1
Browser: Chrome Version 32.0.1700.107

Thank you in advance for any help. Really looking forward to following TS's development and playing.
