FP19: Google Chrome skips frame display rendering when as3 code executes more than 50-70ms

Here is a problem:

We develop a game that contains a lot of moving objects and animations (https://apps.facebook.com/klondikegame/). In latest version of Google Chrome and FP19,0,0,226 our users report performance lags. In Firefox nothing changed.

Profiling with Scout showed that display rendering ocures not in each frame that needs to draw or redraw something. If as3 code executing takes 50-70 ms - rendering is skipped. It can take up to 10 frames without display rendering.

Users see very sharp animation.

Session from Chrome :: lots of frames without display rendering

Session from Firefox :: display rendering in each frame.

Is there a solution to make display render work correct in Chrome?

Cn it be an Adobe issue?
