Rounded corners do not match corners in the shape

Hello.

If I don't load the source to the ImageView with Glide, I see corners are matched each other (see screenshot 1)


But when I using

```java
Glide.with(mViewImage.context)
.load(movie.coverUrl)
.transform(CenterCrop(), RoundedCorners(roundingRadius)) // in the my case roundingRadius = 6dp
.placeholder(R.drawable.ic_placeholder)
.into(mViewImage)
```

I see in some images the corners don't match (see screenshot 2)


I don't understand why this is happening. I will be glad for any help.
