A few weeks ago I had one of the seldom moments in which I had to use Internet Explorer 6. I examined some memory usage oddities in connection with the AlphaImageLoader object when I noticed a strange rendering behavior regarding the proprietary CSS attribute filter. I just added a simple filter like

<span style="filter:Alpha(opacity=100, style=0)"></span>

and my text just looked blurry.

CSS filter with ClearType
Text with ClearType enabled
CSS filter without ClearType
Text without ClearType


The text appears blurry only if ClearType is enabled.

Did your noticed this behavior by yourself? If you have any experiences with the attribute filter in connection with ClearType, please let me know!
