Hi,

as far as we can reproduce this results from JTS intersection check that 
seems to have some problems with a few of the geometries from the 
underlying shape file. Can you check if your code ( 
org.deegree.graphics.displayelements.PolygonDisplayElement ) has 
commented out this:

 public void paint( Graphics g, GeoTransform projection, double scale ) {
       
        if ( feature != null ) {
            ( (ScaledFeature) feature ).setScale( scale );
        }
        try {
            if ( geometry == null ) {
                return;
            }
            // a local instance must be used because following statement may
            // changes the original geometry

            Geometry geom = geometry;
/*           
            try {
                Envelope env = projection.getSourceRect();
                env = env.getBuffer( env.getWidth() / 20d );
                Surface sur = GeometryFactory.createSurface( env, null );
                // cut edges outside the visible area
                geom = sur.intersection( geometry );
            } catch ( Exception e ) {
                // use original geometry
            }
*/      
...

if not so, please update your WMS. If so please mail again so we must 
look for another possible reason.

best regards

ANDREAS
