Public bug reported: Look at this: https://code.google.com/p/chromium/issues/detail?id=529097
I'm almost sure that it's a bug in Ubuntu, not in Chrome, and that I observe it in Chrome just because it's the only application I ever use that goes fullscreen. Note that it's not systematically reproducible, it's just random. When it starts happening there's no workaround other than logging out and in to Xorg. I guess it's related with other window-foreground-background-order-is-a -complete-mess bugs.
