I have a few divs with a repeating background PNG (that as an alpha channel set to ~50% opacity); the purpose is to give a white transparent background to the divs. The divs render great in all current browsers. But when I call my Cufon code to replace certain text on the screen, the backgrounds seem to fade out in a gradient fashion from top left to bottom right (in IE only). It doesn't seem to effect all PNG backgrounds, just certain ones.
Something with Cufon is definitely getting in the way of rendering the transparent PNGs. Has anyone ever seen this functionality?
Cufón wasn't causing the problem; it was just masking it. The real problem was the fact that I was using transparent .pngs that were 1px x 1px. IE will render them incorrectly and fade them out; almost as if they were being stretched beyond limit.
