[OpenLayers-Users] Canvas renderer causing fill in style, map, to be ignored

[Rob Hyx]

So just to add a bit more information to the issue I'm still having.
It appears to only be with polygons that have holes 'cut out' in them.
Solid polygons fill in fine with the canvas renderer. I found this
bug: http://trac.osgeo.org/openlayers/ticket/3130 which doesn't
mention anything being broken, but rather an inefficiency in the way
such polygons are rendered. Has anyone else encountered this: polygons
with a fill color, that have holes in them, are not filling in with a
canvas renderer?

Thanks in advance.
