Build me a Linux app for frame generation that helps games look smoother, like the Lossless Scaling frame generation idea. I want a simple way to turn it on, make it work across common desktop setups, and show clear status so I can tell when it is active.

Keep the experience straightforward, with a small settings screen or config flow for enabling it, choosing the right display and game window, and adjusting quality versus performance. If you need to check current setup details or best practices, look up the latest docs online first. I also want it to be easy to tell when something goes wrong, with helpful messages instead of silent failure.

Please make it feel polished and ready to use, not like a rough prototype, and focus on making frame generation work reliably on Linux for regular users.
