Chrome's bug code

gistfile1.js

var canvas = document.createElement("canvas");
canvas.width = canvas.height = 300;
document.body.appendChild(canvas);
var ctx = canvas.getContext("2d");

var m = document.createElement("canvas");
m.width = m.height = 100;
var mctx = m.getContext("2d");
mctx.fillStyle = "#f00";
mctx.fillRect(0, 0, 100, 100);

ctx.transform(1, 0, 0, 1, 1, 0); // problem!
ctx.fillStyle = ctx.createPattern(m, "");
ctx.fillRect(100, 100, 100, 100);
