DropShadowFilter: Not working 100% like expected on HTML

Hi,

I have a drop shadow filter for our main bar buttons. We use the same instance for each button but have different renderings.

The declaration and definition looks like:
public static var PF_MAINBARCOUNT_TEXT_SHADOW_FILTER: DropShadowFilter = new DropShadowFilter(1.0, 0.0, 0x000000, 0.5, 2.0, 2.0, 64.0);

Please see attached a screen shot:

So on the left you see the filter on the text “310” but on the forth button from the left there should be a number visible as well. Same with last button right. This btw is a relatively new issue.

Any ideas?

Many thanx and

Best regards
Andreas
