Anyone successfully using gamescope to play?

So, I was trying to use gamescope to run the game. I wanted it to have a "dedicated window" as the game occasionally behaves weirdly when I move back and forth from desktops (using sway here). However, after activating gamescope on lutris, the league client never opens. I get the Riot Games window alright, but after clicking on league, it doesn't load past the golden letters.

Anyone got it working somehow?
