When launching the game using the latest Proton-GE (10-26) it only shows white screen and the game audio can be heard; this means the game didn't crash and the issue lies with the display. I tried using Proton-GE 10-25 and the issue persists but this time the screen is black and the game cursor is visible.
Additional info which might be relevant: i'm on Fedora 43 KDE, i'm using the flatpak version of Heroic, and i'm using a laptop with hybrid GPU.
