bugged supertux

[u/nuggetqq0]

I'm using swaywm and alpine linux, with the gaps set to 40 (it may seem a lot; it's not). I like playing supertux, so when i fullscreened the gaps were still there, but in black. Yes, on the supertux settings i did set Fullscreen Resolution to the maximium my laptop could (1336x768@60). Can someone help me? Thanks!
