Saw that example but it does not show how to map the texture to a buffer. It uses another camera as the destination of the texture. Neither headless ofc.
Do you think this this approach could work for my use case? https://gist.github.com/Niedzwiedzw/75b97a6cb93b2872d9523151966a3951

Maybe in combination with the headless approach here (in combination with 'without winit')? https://github.com/bevyengine/bevy/blob/main/examples/app/headless.rs

I found this question in the Q&A which could also be an option as Slint Image supports being created from an OpenGL texture but it hasn't been asnwered yet:
