STR:

1. Open http://www.syntensity.com/static/mams/mams.html and start playing the game.  When you finish a level, the game renders your moves during that level as the two gray rectangular boxes are drawn to the screen.  We perform extremely badly when this happens.

According to a profile, we seem to be spending all of our time in DrawTargetCG::DrawSurface calling CGContextDrawImage here: <http://mxr.mozilla.org/mozilla-central/source/gfx/2d/DrawTargetCG.cpp#264>.

How do we compare to Safari on 10.6?

Safari doesn't support typed arrays so I can't really tell...

This is due to another bug, which I have fixed.  A new version of the game which does not have that bug will be available in a few minutes.

I see this on Linux as well. Looks like CPU usage goes up when showing the replay stuff, and also when showing a dialog box when you walk on it. Something to do with blitting (drawImage) with alpha perhaps?

Need to re-evaluate this when it's back.
