Steps to reproduce:
http://hg.mozilla.org/mozilla-central/rev/0d3b17a88d5f
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/18.0 Firefox/18.0 ID:20120918030553

When I test Bug 792032, I notice a rendering problem.
This happens since Firefox6.0 and later.

Note, 
It is necessary to disable HWA to reproduce the problem due to Bug 792032 in Aurora17.0a2 and Nightly18.0a1.

Steps to reproduce:
1. Open http://www.themaninblue.com/experiment/Blobular/
2. Drag and move around

Actual results:
  Extra SVG arc rendering

Version: 6 Branch → Trunk
Depends on: 929011
Something else must have fixed it. A trunk build without bug 929011 is still OK.

Surely the patches about Moz2D and SVG from Jonathan Watt.
Strange. None of my patches should have been capable of fixing this.
