When ran, it crashes my program. This does not happen when setting any different opacity for `b` (instead of `b.opacity = 1`), or when not setting the frame for `b`. Why would this happen?\r\n\r\n    import visual as v\r\n\r\n    f = v.frame()\r\n    b = v.box(frame=f, opacity=0.5)\r\n    b.opacity = 1\r\n    b.visible = False"}}
