> It would be good to also support Wayland compositors without GTK.

So, which text and vector renderer are you proposing? That's not snark, that's a real question.

A GUI that can actually scale requires both a vector rendering engine and a text rendering engine.

On Linux, that's Cairo and Pango--which are Gtk.

I believe that your only other open source vector engine is Skia, from Google.

Am I missing any other options?

I was going to write that there are several, but you already mention most of them. You say though:

"On Linux, that's Cairo and Pango--which are Gtk."

Yeah, they're not really GTK.

Or in any case that's not what people mean when they say they wished a Rust GUI that doesn't use GTK. They mean one that doesn't use GTK+ the lib and widgets, not whether it can use Cairo and Pango...

Qt. It supports Wayland. It can do high DPI scaling.

Can you pull the Qt vector rendering engine out and use it independently to render to a non-Qt surface? I've never heard of anybody doing that.

Skia is a decent option, or if it has to be written in Rust, then something Rust based.

One can use Cairo and Pango without GTK?

To a certain extent. You can probably punt the UI widget stuff. However, I suspect certain things like glib are required dependencies.

Cairo does not depend on glib,, but pango does.

There's also Graphite (still alive?) that doesn't...
