Glide: Placeholder is not replaced with loaded image, instead image is drawn in top of placeholder

[minas90]

Per doc: When a request completes successfully, the placeholder is replaced with the requested resource.

Actually it's not replaced, but instead it's show bellow the loaded image which causes expensive GPU overdraws, so with placeholder our recyclerview is jerky on low end devices.

            GlideApp.with(context)
                    .load(link)
                    .diskCacheStrategy(NONE)
                    .placeholder(R.color.placeholder)
                    .error(R.color.colorAccent)
                    .centerCrop()
                    .transition(withCrossFade())
                    .into(imageView);

After some research I realized that if I pass

       DrawableTransitionOptions drawableTransitionOptions = new DrawableTransitionOptions().
                crossFade(new DrawableCrossFadeFactory.Builder().
                        setCrossFadeEnabled(true)
                        .build());

to .transition() instead of withCrossFade(), behaviour is different and placeholder is removed after cross fade is finished.
Why default behaviour is not like that?
Is it safe to assume that with code like this performance will be better because of less overdraws or removing placeholder is more expensive?
