Software information

Game: Disney Speedstorm. I tested low and medium settings. The game shows black squares on characters and cars, and the performance is also really poor when compared to native Windows (though that's another issue). Please check the attached screenshots:

Since you're on Intel, can you test if the same issue occurs on AMD or Nvidia, since Intel support for vkd3d-proton is known to be spotty?

I tested on a system with AMD (RX 570 4GB) and the issue is gone. This is specific to Intel Graphics.

Both systems are using the same distro (Fedora 40) and DE (KDE Plasma 6.2).
