Do you have a stack? What if you remove the canvas stuff in there? (The repo is here https://github.com/ehsan/webaudio-tests)

(The > repo is here https://github.com/ehsan/webaudio-tests) The stacks are not useful because they are random Java exceptions. This looks like a canvas leak, not a Web Audio leak. If I comment out biquad.html's canvas code, then the leaks "go away": https://people.mozilla.com/~cpeterson/webaudio/biquad.html

That's terrible. This page paints three canvases on every refresh driver tick... This could be the kind of bug which would affects canvas 2D games. Vlad, have we seen this on such games on Android?

I'm pretty sure we had a recent canvas leak on mobile, but I think it's been fixed in the previous day or two..

Chris, can you please test this again?

I tested today's Nightly build (2013-05-16) and the canvas leak seems to be fixed. :D

Bug 870165 was the leak fix.
