This is getting interesting... Just saw here
@ steam community forum. I use 1920x1080 monitor, the issue was there, in native full-screen, as well as any windowed resolution I tried.
After reading the above post, I forced full-screen 1600x900 (.config/unity3d/CreativeForge\ Games\ S.A./Hard\ West/prefs), and voila! Menus are back! LC_ALL=C ain't necessary, but full-screen is a must!
It turn out that vertical resolution setting >= 1000 will cause the issue, as well as any resolution in windowed mode. Setting this weird 1920x972 full-screen resolution in prefs also worked. WTF?
