The movement is strange when there is shadow in text style. #47

Text does not flow naturally when I run this code

Marquee(
            text: "Hello",
            style: TextStyle(
                color: Colors.green[100],
                fontSize: 100,
                shadows: [
                  Shadow(color: Colors.green[300], blurRadius: 20 / 2),
                  Shadow(color: Colors.green[400], blurRadius: 20),
                  Shadow(color: Colors.green[500], blurRadius: 20 * 3.0)
                ]
            ),
            scrollAxis: Axis.horizontal,
            crossAxisAlignment: CrossAxisAlignment.center,
            blankSpace: 20,
            velocity: 300,
            pauseAfterRound: Duration(seconds: 0),
            startPadding: 10.0,
          );
        }

It's strange only on the simulator. It's okay on the device...!!

That is pretty weird. I suppose, rendering text shadows is pretty resource intensive. Although the widget should actually only render the texts as they newly come into view and use cached versions the rest of the time. Since this only affects the simulator, I don't think I'll take any further action. Is this still a priority problem for you?
