Symptoms

If you use DXVK to render your poster, you will crash when using volumetric lighting, and the polygons will be visible on your models.
If you use Wine's Open Gl, volumetric lighting will work, polygon problem is gone, but AO does not work, resulting in flat looking models.

Reproduction for DXVK

1. Enable DXVK for DirectX 9
2. Create simple scene
3. Enable volumetric lighting on lighting
4. Try to export poster
5. Crash
