Actually, a lot of the early Linux desktop was hampered by this exact problem. I remember in the late 2000s experiencing segfaults constantly in a lot of applications, Mesa/X11, the kernel, and even the desktop environment itself. You had to spend a lot of time tracking down a setup that works and sticking to it when you find it. It's gotten remarkably better since then, but GNOME Shell is still really fragile with segfaults when developing extensions for it. That said, this is not the sole benefit of Rust. It is more of a side effect of aliasing XOR mutability than the primary benefit of Rust as a whole. Let's take a look at the C and Vala landscape as a comparison. Neither support message passing with channels, and async support is virtually an unmaintainable hack. Vala has generics thankfully, but C doesn't have generics and it's really bad. It also doesn't help that your only options for building software is pretty much almost entirely GLib and whatever sparse set libraries might be available for the package manager. Whereas with Rust there's a vast immutable repository of libraries you can leverage, and publishing open source libraries on the platform is easy.
