Terrain should be rendered now (tessellation shaders are implemented in Wine as of commit 38d5b29ae172a96e70b45a6a5fcd03dbf72b2df1).
Yep, missing / transparent surfaces now look fixed!

Occasional yellowness on the distant landscape still shows up though (but less than before), and that visual threads-like artifact too (it seems to depend on lighting). Geralt's hair is still black.
