Map generation is broken in Northgard game in single player mode. See screenshot. Game developers describe map generation process as follows [1]: "The game rendering seems to be working fine, only map generation seems to be broken on some drivers. This involves rendering 2D vectorized shapes and then reading back the resulting graphics buffer. Nothing fancy, but we had some issues in OpenGL with some Intel HD drivers on Windows in the past. Using DirectX (same code, just different driver) did fix the issue for these users."
Map generation is working fine with llvmpipe driver (LIBGL_ALWAYS_SOFTWARE=true).
OpenGL renderer string: AMD Radeon (TM) R9 380 Series (TONGA / DRM 3.19.0 / 4.14.26-gentoo, LLVM 6.0.0)
