I have a website with 529 pictures but few of them fail, with Lighthouse 7.5.0, with the following message:

Expected size

Here a sample:

<!doctype html>
<html lang=en>

<head>
    <meta charset=utf-8>
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <title>Buggy?</title>
</head>

<body>
    <picture>
        <source width="293" height="62" media="(max-width:768px)" srcset="test293w.png" type="image/png">
        <source width="400" height="85" media="(min-width:769px)" srcset="test.png" type="image/png">
        <img src="test.png" alt="text webpagetest.org">
    </picture>
</body>

</html>
