So I am fairly new to AS3 (and to flash for that matter). I have been learning for about a month or so. For my latest project I have been playing around with particle effects, with the ultimate intention of learning how to effectively use them in games.

I have created a mouse trail effect, fire. This is also the first effect I have used blitting for, as well as used an embedded png as a bitmap.

I have it posted on my website, just go to [http://www.starchukgamedesign.com](http://www.starchukgamedesign.com) to preview.

When I look at that animation, I see the rectangle background flickering at certain parts during the animation (even though I set this to transparent). Though it is not really that noticeable, I am not sure if there is any way to get rid of it.

Any C&C would be grealy appreciated. Feel free to comment on my code as well. Thanks!

Edit: Solved. All that I had to do to fix was set the stage quality to low:  
stage.quality = StageQuality.LOW;
