Default MemoryCachePolicy fails in a RecyclerView (default imageLoader & default parameters)

When I load an Image from an URL with the following code and reopen this screen, the ImageViews are mostly just blank. (probably due to caching issues)

fun ImageView.loadUrl(url: String) {
    load(url)
}

When I change the CachePolicy of the memoryCache to anything except CachePolicy.ENABLED (even to READ) the images are shown properly on every attempt, e.g.:

fun ImageView.loadUrl(url: String) {
    load(
        uri = url,
        builder = {
            memoryCachePolicy(CachePolicy.READ_ONLY)
        }
    )
}

I guess the expected behaviour would be showing the cached bitmap, and then replace with the image from the network call. When I tried to debug this with the callbacks in target, onStart and onSuccess were successfully called. Unfortunately I cannot view the bitmap on debug there because of bitmap configuration issues.

When i tried to build a small sample, I found the source of this issue:

The RecyclerView had hasFixedSize = true and the list got an empty list, and afterwards the real dataset, which was causing the issue obviously. I have still no idea, why it worked at the first attempt, and failed at the second one, and why the memory-caching of coil is affected by that.

Nevertheless thanks for your support.

Hmm those logs are the expected behaviour. Do you have a small sample that reproduces the bug? It’s not clear what the root cause is based on the logs and I’m not able to reproduce locally.
