Bug Description

I noticed this earlier when running the peacekeeper tests, that the canvas does not display any content on the build of Firefox we have in quantal. This also happens at http://chrome.angrybirds.com/ (although, there are occasional flickers of corruption on mouseover).

- This is broken on all builds I've tried with gcc4.7 (and is not dependant on PGO)
- It works when building the same version of Firefox with gcc4.6
- It is still broken even with accelerated layers disabled (layers.acceleration.disabled=true)
- It affects both 2d and webgl

Ok, this is actually because of https://bugzilla.mozilla.org/show_bug.cgi?id=754554. Turning methodjit off for content makes the issues go away.
