Curious - how did you get League to work? It’s been years since I’ve attempted to play it on Linux, and it’s always been janky at best, or not work at all.
Just followed the tutorial from leagueoflinux + killed the client process after the initial download, restarted and worked like a charm. It’s a bit laggy in champ select but in game it works well.
League definitely works, I am playing it on my main PC (running Arch) and on my Steam Deck.
There have been quite a few upgrades to the Wine version and the script, you should now be able to get it running just fine using the standard Lutris script with maybe some additional steps from /r/leagueoflinux wiki (can’t remember exactly anymore, been a while since I installed it)
Of course, still expect standard League client bugs, but other than that it works perfectly!
