OK, I've seen that issue happening sometimes along with a different font rendering. Though I'm not able to reproduce it, seems to happen randomly in pages with web fonts. Not really a bug in light-themes, I'm marking this affecting chromium. If you know how to reproduce this consistenly, I reccomend you to file a bug upstream against Chromium at <http://crbug.com>
