I'm using Awesome tiling window manager, which supports Extended Window Manager Hints and relies on them to determine whether to treat clients as fullscreen or as regular tiled or floating windows. For some reason, games that run through Steam Play and use exclusive fullscreen don't have a fullscreen hint while windows that use borderless fullscreen do. See two screenshots below in case of Yakuza 0 with improvised debug notifications. First is with Window Mode set to Fullscreen (notice how lower (newer) notifications say "Fullscreen: false") and second is with it set to Borderless (notice how notifications say "Fullscreen: true").
Affected games
Potentially all games with exclusive fullscreen. Tested on: #2309 (no borderless option) #492
Need for Speed Heat
Current workaround
Attach toggling fullscreen to a keybind (default is Mod4 (Super) + F). Or do some trickery in the configs
