I have seen this as well. It happens whenever you set the "alpha" value
in IE7.
It even happens if the value is set to 1.0, but a fix in OpenLayers 2.6
removes
the "alpha" value if the opacity value is greater than 1.0.
(OpenLayers.Util.modifyDOMElement line 191).
I'm fairly sure its an IE bug.

no, mapserver, but it's a typical client problem.
when the polygon is filled, it looks quite ok, because only the outline
border is wrong, but with lines and labels, whaouh, so crap !
when opacity is 1 or format is standard PNG, the problem doesn't show up.

Hi devs,
When displaying a WMS layer (AGG image) with some transparency on IE7,
it shows ugly grey pixels surrounding the borders. I guess it comes from
a mishandling of the antialiased pixels from AGG. Any trick to hold that ?
Thanks
Guillaume
