when you put polygon on the RS data, you get fragmentation

[xiaowenjin]

My question: when you put polygon on the RS data, you get fragmentation，then I change the depth priority of the polygon to 1, nothing happen, change it to 100000, better but still not good. OK, I use Polygon to Raster, no fragmentation any more, but another question is how can I keep the color, if the polygon has many symbol, you cannot change it one by one. I did not find how to do. By the way, my pro is 1.4. Thank you!
