I don't know how I could reproduce this consistently, but I'm affected by this bug. Shortly after encountering it I had a crash that seemed to restart the display manager/X entirely, so I'm sure state was lost, but if there's any information on what to do to properly gather information on a bug like this I'd be happy to help.
