    Hello,
    I've been working on a sky rendering and weather system for Unity. Recently I had a spare hard drive so I wiped it and installed Linux Mint on it. Out of curiosity, I wanted to test SkyRay on Linux. So I installed 5.6.1xf1 and tried to run the project. It for the most part runs just fine, except for one thing.

    Notice how the entire terrain is in shadow. Additionally, these bizarre quads of random(?) texture data appear floating in midair. If, however, I disable Draw trees on Unity's terrain, both issues vanish completely. Additionally, this project has the Critias tree system in it (available for free on the asset store) which uses GPU instancing for better tree performance. It does not run in the scene view, but allowing it to run in Play Mode (which disables Unity's tree rendering and replaces it with custom rendering) also fixes the graphical glitches.

    Any idea what could be causing this?
    More information about my system:

    OS: Linux Mint 18.1 Cinnamon 64-bit
