Description

1. Steps to reproduce:
   1. Create a symbol in the Flash IDE and apply a Filter (Bevel, Glow, etc.)
   2. Parent that symbol in an mx:Image tag within a Group. (Best if it's in a Group that is in another Group.)
   3. Try to use a Fade effect (either mx.effects.Fade or sparks.effects.Fade) to fade the Group out and back in.

1. Actual Results:
   What you see when you combine those elements above is a 1-frame, fully-opaque flicker after the Fade has completed (if fading out) or before it begins (if fading in).
   This flicker is noticeable and obviously not an intended part of the animation.

1. Expected Results:
   The symbol and its parent(s) should fade out and back in smoothly, without a flicker.

1. Workaround (if any):
   The most reliable work-around so far seems to be avoiding GroupBase components.

I posted on the forums about this as well but have not received any input:

You can see example code demonstrating this bug there.
I've been able to reproduce this bug using both Flex 4.1 and 4.5
