Blending with glitchy artifacts

[FlashBulb]

Does anyone else have this issue with Blend Modes in Flash?

I have a background graphic that's like clouds, and another similar graphic moving over it in Hard Light blend mode. That's working fine, looks cool enough.

Then I put a 50% alpha blue rectangle over it, and it causes some glitchy-looking effects.

Example here (http://www.mikesteffler.com/example.html), please have a look. You can see the issue in the lower-right part of the screen.

Has anyone else dealt with this before? I was hoping that an upgrade to CS5 would take care of it, but there was no change.

I've had to deal with this for some time. I find it hard to believe I'm the only one.

You probably are not the first one to experience this but you are the first one who showed me this problem... So, I'd say it is a bug on Flash IDE???

So... then there's no fix? Do you ever use Blend Modes in Flash?

Do I? Nope... I knew about the functionality but I never had reason to use it...
