From my understanding, at least one other necessary component is dxvk, and that wine is not enough.
If I dont use lutris or some other manager, how can I game on linux? do I have to configure dxvk? do I need soemthing else too? vulkan?
Is there a guide that explains it?
Have you tried Gamescope? I experienced similar issues with a lot of older visual novels. Gamescope was the cure-all for windowing issues like this. That said, if WineD3D works better than DXVK for the game, there’s not much reason to look into it.
