Device/Android Version:Android 7.1.1 (API 25)

Issue details / Repro steps / Use case background:
As per https://stackoverflow.com/questions/49817432/glide-placeholder-image-retain-if-transition-is-used-but-disappear-when-transit

Glide load line / GlideModule (if any) / list Adapter code (if any):

    Glide.with(this)
            .load("https://flybubble.com/media/wysiwyg/images/home/mainpage-box-5L.jpg")
            .transition(DrawableTransitionOptions.withCrossFade())
            .apply(RequestOptions()
                    .placeholder(R.drawable.placeholder)
                    .centerCrop()
                    .transforms(CenterCrop(), RoundedCorners(1000)))
            .into(my_image_view)

Will show the placeholder background after the image loaded

    Glide.with(this)
            .load("https://flybubble.com/media/wysiwyg/images/home/mainpage-box-5L.jpg")
            .apply(RequestOptions()
                    .placeholder(R.drawable.placeholder)
                    .centerCrop()
                    .transforms(CenterCrop(), RoundedCorners(1000)))
            .into(my_image_view)

Will not show the placeholder background after the image loaded

@sjudd From the link you pasted, "If you are loading transparent images with placeholders, you can enable cross fades by adjusting the options in DrawableCrossFadeFactory and passing the result into transition().". The doc suggests to enable transition, but problem here occurs when transition is enabled and does not occur when transition is disabled.

any updates on this @elye @sjudd @hqzxzwb?

I'm not sure what more I can offer here, there's a multiple paragraph explanation in thee doc linked above.

Or are you saying that (from the doc link above) setting cross fade enabled doesn't work either:

DrawableCrossFadeFactory factory =
        new DrawableCrossFadeFactory.Builder().setCrossFadeEnabled(true).build();

GlideApp.with(context)
        .load(url)
        .transition(withCrossFade(factory))
        .into(imageView);
