[BUG] linux version - no textures in dark areas


#1

latest steam linux version. Kubuntu 16.04 16b, 16g ram, nvidia 660ti w 387.34 drivers.

right from the introduction cutscene, and in game, in darker areas textures are replaced with a red wireframe mesh.
tried reverting back to 384 drivers. tried changing video options systematically, but to no avail. also tried windowed/fullscreen but no changes.
