With Titan Quest for instance, some launch option titles cut off essentially after the game name. The modal window can't be expanded (by dragging from the edges) and there's no tooltip text. There's no easy way to always select the preferred option.
The only way I'm aware of is to view the options on SteamDB (
steamdb.info/app/<app ID>/config/), and perhaps by parsing local Steam configuration files.
Steam build Jan 16 2022, Linux (settings → interface → 'enlarge text and icons based on monitor size' is enabled, essentially mandatory on 4K displays)
