Fair - point still stands though - the application only has a single breakpoint defined at 600sp from a cursory glance, the lack of an ultra-wide specific layout is just because it hasn’t been implemented rather than a shortfall of GTK (though I’m not sure you would even want to make the message view wider, as it would impair readability)
That looks like it’s just wrapping a WebView, is it not?
It looks like the CSS is just capping the container class width at 1440px, which has nothing to do with GTK
It’s Fractal, a matrix client, not a webview: https://gitlab.gnome.org/World/fractal
