So I have been working on a game in HTML5 canvas and noticed that the games lags and performs much slower when hardware acceleration is turned on in Google Chrome then when it is turned off. You can try for yourself here

From doing some profiling I see that the problem lies in drawImage. More specifically drawing one canvas onto another. I do a lot of this.

Hardware Acceleration on. Profile while hardware accelerated

Hardware Acceleration off. enter image description here

Is there something fundamental I am missing with one canvas to another? Why would the difference be that profound?
