I noticed the OSD speaker was overly large when using Metacity Compositing. Turning the enhanced effects off put everything back to normal. I do not use Compiz, so I cannot verify it does the same thing there. This narrows down where the size issue lies, so if anyone has any further suggestions, please share.
