[Pharo-project] World intermittently becoming a mess

Every once in a while, in my 1.3-rc image, the World becomes a mess. Specifically: * moving windows without the fast dragging setting enabled leaves a trail * previews from hovering over the task bar remain in the World and don't delete themselves when the mouse is no longer over the task bar I haven't been able to reproduce it, but it's happened a few times. Has anyone else experienced this?
