### Reproduction

Create a layout like this:

```

```
In activity just load any gif:

```
String url = "https://cdn.emogi.com/cxp/zyw/zywld-medium.gif?4a-C46DEX-0-beiiuj24cgad79rvike0";

Uri uri = Uri.parse(url);
SimpleDraweeView fresco = (findViewById(R.id.fresco));
DraweeController controller = Fresco.newDraweeControllerBuilder().setUri(uri).setAutoPlayAnimations(true).build();

fresco.setController(controller);

```

If you remove `fresco:roundWithOverlayColor="#ffffff"` It works fine

### Additional Information

* Fresco version: 1.9.0
* Platform version: Only happen to Android 7
