Hello @brmmd-12, you're probably already aware, but the video drivers for Intel's Haswell generation provides an incomplete implementation of Vulkan. This is a general requirement for Proton. Graphical artifacts or crashing is expected. Sorry, but your GPU generation is unsupportable by Proton.
Also, while it can useful for troubleshooting, PROTON_USE_WINED3D=1 is not considered supported. If you want to pursue any misrendering with that render path, then reproduce the issue with vanilla wine, then report your findings to the upstream wine project.

Symptoms
Cows only show horns and hoofs (don't know if it's the same for other livestock or not), characters/buildings/dogs are displayed correctly. When trying on Windows 10 with the same machine this kind of problem doesn't occur.
