I see this more often than I'd like and I think this is a race condition with custom fonts. It calculates the bounding box for words, then the font is downloaded, the font is rerendered, but the bounding box isn't updated for the new font's metrics. A reload, since the downloaded files are now cached, usually fixes it.
