Hi, the game started regularly stuttering for me seemingly for no reason, presumably after an Arch Linux update.
On Steam it was suggested to update the bundled SDL2 library with a newer one provided by flibitijibibo: https://steamcommunity.com/app/504230/discussions/4/4336474207083138770
Unfortunately his link doesn’t work anymore, but it turns out that the issue is fixed by just removing the bundled SDL2 lib entirely and instead letting the game use native libraries (sdl3 with sdl2-compat).
I was gonna leave a comment on that Steam forum thread, but I don’t own the game on Steam, so I’m writing a post here instead. :)
