See attached testcase. I'm updating a frame counter once per frame at 30 fps in a canvas, and it isn't updating 30 once for every draw operation; sometimes my counter stops incrementing. I'm guessing we're not invalidating on every draw operation?
This is a regression since Firefox 4 shipped.

I'd guess this was caused by bug 622072.

It's the "canvas.width = canvas.width;" reset in there that causes the problem...
