If you just file a bug on Bugzilla (https://bugzilla.mozilla.org/ https://bugzilla.mozilla.org/) in the Core: Graphics component with a reproducible testcase that will probably get people looking at it pretty quickly. For more one-on-one contact I'd suggest the #gfx channel on the Mozilla IRC, although that tends to work best if you know who to reach out to specifically. The gfx newsgroup (https://groups.google.com/forum/#!forum/mozilla.dev.tech.gfx https://groups.google.com/forum/#!forum/mozilla.dev.tech.gfx) might also work to call attention to a particular issue. You can probably setup an e-mail contact through one of those channels if that's what you prefer.
