IE8 PNG Gradient Transparency Problem

The following graphic illustrates an issue with png transparency in Internet Explorer, that I am unable to resolve.

The transparent graphic is the following image.

I realize that it might be invisible on white background, so here's the inverse of the same image to aid understanding.

The idea is to provide a soft lead-out which works nicely on Chrome/FF/Safari/Whathaveyou, but obviously one can't have nice things and IE wants to stand out. I would very much appreciate any help on this matter.

EDIT: I've read someplace that combining opacity effects and transparent pngs is not well supported in Internet Explorer. By removing the opacity effect and making suitable changes to my png graphic, I was able to reproduce same a开发者_运维技巧nimation across all major browsers.

You cannot safely mix legacy DirectX Opacity Filters and transparent-PNGs. In IE9, you can use native CSS3 Opacity safely with PNGs without the problem you encountered.
