You have two options that I can recommend: 
 * Switch to a WMS.Untiled layer, possibly with a 'ratio' of something
   like 1 set on the layer:
     
     new OpenLayers.Layer.WMS.Untiled("Name", "URL", {'params':'here'}, 
                                    {ratio: 1.0});
 
 * Turn down the buffer on your WMS layer:
     
     new OpenLayers.Layer.WMS("Name", "URL", {'params':'here'},  {buffer: 0});
