Seems like you are applying the filter many times. That would be my
guess. Using the filters array makes sure that you apply it only once.
Best, Yotam.

Thank you for the reply.
I tested it using your suggestion, and it seems to behave properly if
I use MovieClip.filters instead of using applyFilter. However, since
I want the end result to be a bitmap (for animation purposes), I
wrote a little workaround code... as follows:
// draw bitmap 1
var glowFilterMC = parentMC.createEmptyMovieClip("glowfilter_mc",
parentMC.getNextHighestDepth());
var glowBmp = new BitmapData(targetMC._width, targetMC._height, true,
0x000000);
glowFilterMC.attachBitmap(glowBmp, 1, "auto", true);
glowBmp.draw(targetMC);
// apply glow filter with knockout
var filter = new GlowFilter(0xFFFFFF, 1, 5, 5, 5, 1, false, true);
glowFilterMC.filters = [filter];
// draw bitmap 2
var outlineMC = parentMC.createEmptyMovieClip("outline_mc",
parentMC.getNextHighestDepth());
var outlineBmp = new BitmapData(glowFilterMC._width,
glowFilterMC._height, true, 0x000000);
outlineMC.attachBitmap(outlineBmp, 1, "auto", true);
outlineBmp.draw(glowFilterMC);
// dispose of bitmap 1 and its holder
glowBmp.dispose();
glowFilterMC.removeMovieClip();
Quite a few more lines of code than the original method, but hey..
it works.
