Can you elaborate on the input latency part? It shouldn't really add any since it's just isolation.
Let's say you press a button on their "pretty looking" encoded stream using your "web browser". The absolute minimum amount of time for your input signal to reach the "machine" actually running the application/game is (on average) 30ms. The next frame of the game which acknowledges your input takes (again, absolute minimum) another 30ms to get from there to you. In reality, it's more like 120ms of "lag" minimum, no matter what anyone does to streamline/prioritize packets/eek out more efficiency.
It's the worst possible problem for playing any game. It's what killed Stadia, it's what killed Amazon's BS game streaming service. Makes a person feel just a tiny bit "drunk"- things taking too long, etc.
You may not "feel" if if you've never gamed locally (normally, game running on your own computer) but it's there and it fucking sucks.
I think what Missphant was asking wasn't "what is input latency" but was "does flatpak introduce more input latency than a 'normal' application". Unfortunately, after a quick search I didn't find any benchmarks. (I didn't look very thoroughly.)
Ohhh! No using flatpak doesn't cause any of that. Flatpak is great.
