98% of desktop apps (at least on Windows and Linux) are already broken by design anyways. Any one app can spy on and keylog all other apps, all your home folder data, everything. And anyone can write a desktop app, so only using solutions that (currently) don’t have a desktop app version, seems silly to me.
If you have root you could just update the kernel to one that lets you do whatever you want on the system, so there’s no way to stop the attacker from viewing the passwords if the app is capable of displaying them.

Linux has a sandbox solution growing in popularity, flatpak.
And Wayland. Xorg is a complete and utter mess
I don’t think apps can read keystrokes for other apps on Wayland.
