293306 - canvas leaks lots of memory

Status: VERIFIED FIXED

(Core :: Graphics: Canvas2D, defect)

Description

I'm not sure what to say here. Open the testcase and reload a few times. Every
reload adds 2MB to Firefox mem usage in Task manager. I noticed that while
playing with canvas, everything suddenly became very slow and Firefox was using
~380MB.

Argh, I have a refcounting loop between the canvas element and rendering
context.  Thought I fixed it a while ago, guess not!  Patch tomorrow.

Should be resolved by the patch in bug 293407.

It doesn't seem to be leaking that bad anymore. That is, nothing that can be
seem in Task Manager :)
