I suggest including 2147483642 not in LTS, but in Ubuntu 24.10 as an experiment. Because I noticed an unpleasant detail. For example, there is a game "Don't Starve," I know there is a native version, but this is just as an experiment with Proton. If you launch the Proton version, you will receive a message when vm.max_map_count = 1048576: "steam_app_218740" is not responding. You may choose to wait a short while for it to continue or force the app to quit entirely. But when vm.max_map_count = 2147483642, there are no problems, everything loads instantly.
