Afaict, https://justinreina.com/lifebook/icons/Lifebook.ico is a 256x256 ico file, it doesn't have other frames. https://justinreina.com/favicon.ico on the other side has multiple frames at 16x16, 32x32, 48x48, 57x57... and so on When looking for a 16px favicon, supposing you're on an hi dpi screen (so the icon must be larger than 16x16 to be shown as 16px), bookmarks will look for a 32px icon. The root favicon (that ideally should be valid for most sub pages) perfectly matches that, while the page favicon is really large and by downscaling it, it may become unrecognizable. Providing a better favicon (either svg or multi-frame or multiple png) that can adapt to normal favicon sizes would likely help. We could probably prefer the associated icon to the root icon, though the visual result would not be the best, we'd end up showing blurry or unrecognizable icons more often. We should think about this, but there's no perfect solution, each choice has its own downsides.(In reply to lucasli from comment #4) > I also encountered the same problem > https://brg365.com/futebol/rb-bragantino-conquista-o-titulo-da-copa-aspirantes-do-brasil-e-encerra-time-sub-23/ This seems to be working fine for me?
