Comment 3 for bug 354451

Eitan, I agree with your idea that hplip is probably drawing its notifications in a non-standard way - they do look subtly different from 'proper' old style notifications. I'd get you a screenshot but I'm afraid the hard drive with my Ubuntu partition is currently away for data recovery and won't be back for a week or so yet (just my luck to have it fail on me days after reporting a bug that needs more info!)

I'll post a screenshot when it returns.
