Hi, I'm building a GTK4 / libadwaita app.
I noticed that minimize/maximize icons are bigger on the Windows build.
(gvsbuild 2026.4.1, GTK 4.22.2, libadwaita 1.9, Rust 1.95-msvc)

I thought it was GTK's problem, but the problem is gone if I build it on MSYS, so I am reporting it on here.

Here are the cropped images:

let app = Application::builder().application_id("io.github.foriequal0.Test").build();

window.present();
});
app.run()
