I notice in Steam how high the input-lag is when you type in the chat. I would bet that that is because of the containerization. Telegram has this too, Kotatogram somehow does not. I am very much against any containerization.

One of the reasons why I switched from Windows to Linux is the better performance, and then they ruin it with immature containers: making the software slower, causing more memory-waste and in some cases breaking theming.
