What is Linux beta? Can you show how this blurry UI looks on your machine?
Pros: it might solve various issues users of less popular Linux distros have, more secure and transparent to the user.
Cons: it will require moderately high amount effort to integrate properly, both in CI and in Editor — Defold uses OpenGL and file system access to opened project directories that are unavailable by default for flatpak apps. Some other stuff might break too (like developing on device over a local network? it seems that’s disabled as well).
I think it’s an idea worth exploring, but I’m not willing to do it myself
