Poster image not visible

[DanieleMagri]

I've never had problems with posters, but in this case I can't see some images, the format is always PNG, any idea what it could be? Some work, some don't

<model-viewer bounds="tight" src="/assets/GLTFmodels/model.glb" ar ar-modes="scene-viewer quick-look webxr" environment-image="neutral" style="--poster-color:transparent ;" shadow-intensity="1" reveal="manual" poster="/assets/category/thumbnails/image.png" > <button slot="ar-button" id="ar-button"> AR </button> <div class="progress-bar" slot="progress-bar"></div> </model-viewer>

CSS

model-viewer { display: flex; float: left; width: 40%; height: 100%; }

The absurd thing is that if I have a working image, and I move it to a different folder, after obviously changing the url in the code, this doesn't work! And if I try to move the faulty images in the "not working" folder to the "working" one, I change the url, and they still don't work ...

From your description I might guess a server caching problem? See if you can reproduce it on a Glitch and link it here.
